Description

Technical Field

[0001] This invention relates to the field of smart classroom technology, specifically to a remote management method and system for computer classrooms based on LDAP dynamic identity binding. Background Technology

[0002] The statements in this section are provided only as background information in connection with this disclosure and may not constitute prior art.

[0003] Traditional computer classroom management software (such as Veyon and NetSupport School) primarily relies on static network discovery technologies (such as IP scanning and multicast discovery). Teachers typically only see static computer identifiers, such as IP addresses (e.g., 192.168.1.101) or static hostnames (e.g., PC-01). When student seating is not fixed or when using shared computer labs, teachers cannot quickly and intuitively identify which student is sitting at a particular physical computer, hindering precise individual tutoring or behavioral management. Current technology lacks an effective mechanism for real-time, automatic association and visualization between the user's login identity and the physical device identifier, resulting in low management efficiency and failing to meet the needs of precise smart classroom management. Summary of the Invention

[0004] The purpose of this invention is to address the problem that current traditional computer classroom management software mainly relies on static network discovery technology, which can only display static computer identifiers (such as IP addresses or fixed hostnames). When student seating is not fixed, it is difficult to automatically and in real-time associate and visualize the user's identity with the physical device identifier, leading to low management efficiency and failing to meet the precise management needs of smart classrooms. This invention provides a remote management method and system for computer classrooms based on LDAP dynamic identity binding. The core of this system and method lies in constructing a centralized management architecture that integrates the Veyon remote control framework with LDAP directory service as the unified authentication center. Its innovation lies in the fact that when a student logs into a specific computer through their own business system (such as a Java teaching platform), the system can automatically trigger an attribute update for the corresponding computer entry in the LDAP database (e.g., dynamically changing the description attribute from "PC-001" to "Zhang San's computer"). The teacher's Veyon Master software, through the LDAP-based network discovery mechanism, can read and display this dynamic change in real time, thereby converting the traditional static device identifier (IP address or hostname) into intuitive real-time user identity information on the teacher's interface. This invention effectively solves the problem of disconnect between user identities in traditional computer room management, and realizes precise, visual and automated teaching management.

[0005] The technical solution of the present invention is as follows: A method for remote management of computer classrooms based on LDAP dynamic identity binding includes: Dynamic identity binding steps: After a user successfully logs in, the business system on the student's computer automatically calls the LDAP application programming interface to modify the attributes of the corresponding student's computer entry in the LDAP directory server, and dynamically associates the currently logged-in user's identity information with the device identifier of the student's computer. Real-time status discovery steps: The management software on the teacher's computer periodically queries the LDAP directory server based on the configured LDAP network discovery mechanism to obtain the latest attributes of all computer entries, thereby discovering the real-time status of computers in the network and the bound user identity information; Interactive management steps: The interface of the management software is updated based on the latest acquired attributes and the user identity information is displayed first. Based on the received selection instructions for the user identity information, a remote management operation is initiated to the corresponding student terminal computer.

[0006] Furthermore, modifying the attributes of the corresponding student computer entry in the LDAP directory server to dynamically associate the currently logged-in user's identity information with the student computer's device identifier includes: The business system monitors the login events of the student's computer. After detecting that the user has successfully logged in, it obtains the user's identity information and the hostname used as the device identifier. A target entry identifier name is constructed based on the hostname, and an LDAP modification request is generated in memory. The LDAP modification request includes the target entry identifier name, a replacement operation instruction, and target attributes. Based on the preset service account credentials with directory write permissions, a secure connection is initiated to the LDAP directory server and authentication is performed; After successful authentication, an LDAP modification request is sent to the LDAP directory server to trigger the LDAP directory server to execute the replacement operation instruction, dynamically updating the value of the target attribute corresponding to the target entry identifier to a string containing the user identity information.

[0007] Furthermore, the target attribute is a descriptive attribute; The construction of the target entry identifier name based on the hostname includes: The hostname is used as a public name segment, and the target entry identifier name is generated by concatenating it with a preset organizational unit segment and domain name segment.

[0008] Furthermore, the periodic querying of the LDAP directory server to obtain the latest attributes of all computer entries includes: The management software initiates query requests to the LDAP directory server at preset intervals. The query requests include a basic identifier pointing to the target organizational unit and query conditions for filtering host types. Retrieve all computer entries that satisfy the query conditions returned by the LDAP directory server, along with their latest attributes containing the user's identity information.

[0009] Furthermore, the interface of the management software is updated based on the latest acquired attributes and prioritizes displaying the user identity information, including: In the graphical user interface of the management software, the latest attributes are parsed to extract the user identity information; The display name of the student terminal computer in the interface list is dynamically replaced by the user identity information from the static device identifier for visual display. The device identifier is a static hostname or IP address.

[0010] Furthermore, the step of initiating a remote management operation on the corresponding student terminal computer based on the received selection instruction for the user's identity information includes: The management software's interface list receives trigger operations based on the target user's identity information; Based on the device identifier mapped from the target user's identity information, the corresponding target student terminal computer is determined; The management software establishes communication with the remote control client deployed on the target student's computer through a preset protocol, and issues the execution command corresponding to the selected remote management operation.

[0011] Furthermore, the remote management operation includes any one or more of the following combinations: Remote viewing, remote control, screen locking, and message sending are all supported.

[0012] This invention also proposes a remote computer classroom management system based on LDAP dynamic identity binding, comprising: An LDAP directory server is used to store device identifiers, user account information, and dynamically established associations for computer entries; At least one student-end computer is equipped with a business system and a remote control client. The business system is configured to automatically call the LDAP application programming interface after a user successfully logs in to the student-end computer, modify the attributes of the corresponding entry for the student-end computer in the LDAP directory server, and dynamically associate the currently logged-in user's identity information with the device identifier of the student-end computer. The teacher's computer is equipped with management software configured to periodically query the LDAP directory server based on the LDAP network discovery mechanism to obtain the latest attributes of all computer entries, thereby discovering the real-time status of computers in the network and the bound user identity information. The interface of the management software is updated based on the latest attributes obtained and prioritizes displaying the user identity information. Based on the received selection instructions for the user identity information, the software initiates remote management operations to the remote control client on the corresponding student's computer.

[0013] Furthermore, the business system includes an identity synchronization service, which is configured as follows: Continuously monitor the operating system login events of the student's computer to obtain the user's identity information and the hostname used as the device identifier; A target entry identifier name is constructed based on the hostname, and an LDAP modification request containing replacement operation instructions is generated in memory; After completing security authentication using a pre-set service account credential with directory write permissions, an LDAP modification request is sent to the LDAP directory server to dynamically update the value of the description attribute corresponding to the target entry identifier to a string containing the user's identity information.

[0014] Furthermore, the management software is also configured as follows: At a preset period, a query request containing the basic identifier name pointing to the target organizational unit is sent to the LDAP directory server; The latest attributes returned by the LDAP directory server are parsed, and the display name of the student's computer is dynamically replaced with the user identity information in the graphical user interface list of the management software, instead of the static hostname or IP address, for visual display. In response to a trigger operation targeting the user's identity information in the interface list, communication is established with the corresponding remote control client through a preset protocol, and an execution command corresponding to the selected remote management operation is issued.

[0015] Compared with existing technologies, the advantages of this invention are: 1. Breaking through the limitations of static identification, this invention enables visualized and precise management across devices. After successful login to the student's computer system, the invention automatically calls the LDAP application programming interface to dynamically associate user identity information with device identifiers. The static device identifiers (such as IP addresses or static hostnames) displayed in the teacher's computer management software are then dynamically replaced with the aforementioned user identity information. This mechanism completely solves the technical pain point of "disconnect between physical devices and current user identities" in traditional computer lab management. It allows teachers to intuitively and in real-time identify the current real user of each computer, thereby elevating the management granularity from the "device level" to the "user level," providing a reliable basis for precise one-on-one tutoring and behavior control in the classroom.

[0016] 2. Fully automated state transitions enable zero-latency identity-device binding. This invention constructs an automatic update mechanism triggered by system login events. The identity synchronization service (business system) continuously monitors login events in the background and automatically generates and sends LDAP modification requests containing replacement operation instructions, requiring no manual intervention, recording, or verbal verification. Simultaneously, the teacher's end automatically retrieves the latest attributes at preset intervals through an LDAP-based network discovery mechanism, achieving second-level mapping and zero-latency presentation of identity and device binding status, significantly improving the daily operation and management efficiency of computer classrooms.

[0017] 3. The highly cohesive and loosely coupled system architecture boasts exceptional compatibility and scalability. The core logic of this invention is cleverly encapsulated within the interaction between an independently deployed business system and an LDAP directory server, decoupling "identity authentication synchronization" from "underlying remote control." Because the data bus between systems employs the standardized LDAP protocol and basic identifier name (DN) construction rules, this solution can be easily integrated into existing campus unified identity authentication systems. Furthermore, it possesses excellent backward compatibility, seamlessly adapting to various mainstream general-purpose remote control frameworks on the market, significantly reducing the costs of large-scale deployment and system iteration.

[0018] 4. An internal closed-loop security authentication mechanism ensures the security of underlying data and communication. During dynamic identity binding, this invention directly constructs LDAP modification requests in memory and forces the use of preset service account credentials with exclusive directory write permissions to initiate a secure connection and authentication with the LDAP directory server. This mechanism not only ensures that ordinary student users cannot tamper with global directory information without authorization, but also that the entire management process is completed in a closed loop within the internal LAN environment. It supports use in conjunction with physical isolation devices such as one-way network gateways, meeting the extremely high security and compliance requirements of education systems and smart classrooms for core data assets.

[0022] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0023] Example 1 To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0024] This embodiment provides a remote computer classroom management system based on LDAP dynamic identity binding, the core architecture of which is as follows: Figure 1 As shown, the system mainly includes: an LDAP directory server (such as an OpenLDAP directory server), at least one student computer, and a teacher computer. All devices are deployed on the same internal network (e.g., the network infrastructure uses the 192.168.209.0 / 24 network segment) to ensure secure communication between components.

[0025] Specifically, the LDAP directory server is used to store the device identifier, user account information, and established dynamic association relationships of computer entries; the student-end computer is equipped with a remote control client (such as Veyon Client) and a business system; the teacher-end computer is equipped with management software (such as Veyon Master) and configured to discover and manage student-end computers in the network through the LDAP protocol.

[0026] The core innovation of this invention lies in using the aforementioned business system (specifically, a self-built, lightweight identity synchronization service) as a bridge connecting user login events and the LDAP directory, thereby achieving dynamic, real-time, and automated binding of device identifiers and user identities. Based on the above system architecture, this embodiment provides a remote management method for computer classrooms based on LDAP dynamic identity binding, with the specific implementation steps as follows: S1: Dynamic Identity Binding Steps This step is crucial to achieving the objective of this invention. Its core is that after a user successfully logs in, the business system on the student's computer automatically calls the LDAP Application Programming Interface (LDAP API) to modify the attributes of the corresponding entry for the student's computer in the LDAP directory server, dynamically associating the currently logged-in user's identity information with the device identifier of the student's computer. The specific process includes: (1) Student login event trigger: A student starts the operating system on a student-end computer (e.g., the hostname used as the device identifier is PC-001, and the IP address is 192.168.209.101). The business system deployed on the student-end computer (e.g., a self-built Java Web service or a C / S architecture client, i.e., an identity synchronization service) continuously monitors the system's login events. When a student (e.g., the username is student001, and the real name is "Zhang San") successfully logs in using their domain account or local account, the system obtains the user's identity information and the hostname used as the device identifier, and triggers subsequent operations.

[0027] (2) Constructing an LDAP modification request: The business system generates an LDAP modification request in memory. Specifically, a target entry identifier (DN) is constructed based on the hostname. The construction rule is as follows: the hostname is used as a public name segment (cn), combined with a preset organization unit segment (ou) and domain name segment (dc) to generate the target entry identifier (e.g., cn=PC-001,ou=Computers,dc=sxjx,dc=com). The request also includes a replacement operation instruction (i.e., specified as a REPLACE operation) and a target attribute (the target attribute is preferably a descriptive attribute, such as description or other custom attributes such as currentUser). The modification request aims to dynamically update the value of the target attribute to a string containing the user's identity information (e.g., "Current user: Zhang San (student001)").

[0028] (3) Perform LDAP authentication and update: The business system uses a preset service account credential with directory write permissions (e.g., service account DN is cn=veyon-service,ou=Services,dc=sxjx,dc=com) to initiate a secure connection (e.g., using LDAPS or STARTTLS protocol) to the LDAP directory server (e.g., IP is 192.168.209.10) and perform authentication. After successful authentication, the LDAP modification request is sent to the LDAP server to trigger the LDAP server to execute the replacement operation instruction, dynamically updating the description attribute value of the cn=PC-001 entry from possibly being empty or an old value to "Current User: Zhang San (student001)". At this point, the user identity has been successfully and automatically bound to the device identifier of the physical computer.

[0029] S2: Real-time Status Discovery Steps This step demonstrates how the present invention visualizes the results of dynamic binding for teachers. The management software on the teacher's computer, based on a configured LDAP network discovery mechanism, periodically queries the LDAP directory server to obtain the latest attributes of all computer entries. The specific process includes: (1) Scheduled Query: The management software (Veyon Master) on the teacher's computer is configured to use LDAP discovery mode. It will send query requests to the LDAP server at preset intervals (e.g., every 30 seconds). The query request contains the base identifier name pointing to the target organizational unit (e.g., the OU pointing to the computer: ou=Computers,dc=sxjx,dc=com), and query conditions for filtering host types (e.g., objectClass=ipHost).

[0030] (2) Obtain dynamic identity information: The LDAP server returns all computer entries that meet the query conditions and their latest attributes containing the user identity information. For the entry cn=PC-001, the description attribute value obtained by the management software is "Current User: Zhang San (student001)" which was dynamically modified in step S1.

[0031] S3: Interactive Management Steps The management software interface is updated based on the latest acquired attributes and prioritizes displaying the user identity information. Based on the received selection command for the user identity information, it initiates a remote management operation to the corresponding student's computer. The specific process includes: (1) Dynamic Interface Update: In the graphical user interface of the management software, the latest attributes are parsed to extract user identity information. The display name of the student computer in the interface list is dynamically replaced by the static device identifier (i.e., static hostname PC-001 or IP address 192.168.209.101) with the user identity information for visual display (e.g., displayed as "Zhang San's computer (student001)", "Li Si's computer (student002)", etc.). Teachers no longer see a cold device list on the management interface.

[0032] (2) Target Selection and Operation Initiation: When a teacher needs to provide individual tutoring to "Zhang San" in class, there is no need to ask which computer Zhang San is sitting at. The teacher receives a trigger operation (e.g., right-clicking the target) based on the target user's identity information (such as "Current User: Zhang San (student001)") in the management software's interface list. The system determines the corresponding target student's computer based on the device identifier mapped by the target user's identity information.

[0033] (3) Execution and Feedback: Based on the received selection instructions, the management software establishes communication with the remote control client (Veyon Client) deployed on the target student's computer through a preset protocol, and issues the execution instructions corresponding to the selected remote management operation. The remote management operation includes, but is not limited to: remote viewing operation, remote control operation, screen locking operation, and message sending operation. The entire process is based on accurate dynamic identity binding, ensuring the accuracy of management actions.

[0034] Combination Figure 1The interactive flowchart shown clearly illustrates the data flow path and automatic triggering mechanism in this embodiment: First, the student initiates an account login request, which is captured by the self-built business system and then initiates security authentication with the LDAP server, dynamically updating the student's computer's description attributes (e.g., replacing "pc-001" with the user's name). Subsequently, the teacher (VeyonMaster) scans the computer list in LDAP through an automatic discovery mechanism to obtain the updated device and user identity information. Finally, the teacher directly specifies the student's identity target on the interface and initiates a remote connection using the underlying protocol, completing the entire interactive process.

[0035] This embodiment encapsulates the core logic within the business system (identity synchronization service), decoupling it from the standard LDAP protocol and mature remote control frameworks (such as Veyon). This not only completely changes the traditional method of manual recording or verbal inquiry, achieving zero-latency (automation and real-time) binding of identity and device, but also elevates the management granularity from the device level to the user level (precise management), possessing extremely strong architectural clarity and general scalability.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
