Embodiment approach

[0053] This embodiment provides a kind of implementation mode that 802.1X authentication server detects whether the Windows AD authentication server is down, including:

[0054] Step 2a, the 802.1X authentication server sends an authentication request to the Windows AD authentication server according to the preset detection user name and detection password corresponding to the detection user name.

[0055] Before downtime detection, the administrator can pre-configure the user name and password used for detection for the 802.1X authentication server, that is, the detection user name and the detection password corresponding to the detection user name. In the specific implementation process, the 802.1X authentication server sends an LDAP authentication request message to the Windows AD server using the pre-configured account for accessing the Windows AD domain (that is, the detection user name and detection password), so as to send the authentication request to the Windows AD aut...

Abstract

The invention provides an authentication method and system as well as an authentication server. The method comprises the following steps: when a Windows AD authentication server is detected in downtime, a 802.1X authentication server can respectively compare the received user name and password of a client with a prestored authenticated user name and password; when a comparison result is that the user name of the client is same with a first authenticated user name and the password of the client is same with the first authenticated password corresponding to the first authenticated user name, the client can be determined to pass the authentication of the Windows AD domain; and when the comparison result is that the user name of the client is different from any authenticated user name or the password of the client is different from the first authenticated password, the client is determined to fail the authentication of the Windows AD domain. The technical scheme provided by the invention can solve the problem that a user can not work because the user can not be authenticated after the Windows AD server is in downtime.

Description

technical field [0001] The invention relates to network communication technology, in particular to an authentication method, system and authentication server. Background technique [0002] The 802.1X protocol is one of the local area network (Local Area Network; LAN for short) standards formulated by the Institute of Electrical and Electronic Engineers (Institute of Electrical and Electronic Engineers; IEEE for short) 802 committee. The 802.1X protocol is a port-based network access control protocol. Port-based network access control refers to controlling the client's access to the network at the access level of the network. The client accesses the port of the access device in the network (for example: Ethernet Ports of switches or broadband access devices) block all access rights of users to the network by default, and only process a specific protocol packet. That is to say, for a LAN deployed with the 802.1X protocol, when a client (such as a personal computer, etc.) acce...
