(In a wireless network, when a user uses a Web page to log in for authentication, an extended database is generally required as the authentication database, and the AD mobile directory is commonly used as the user database. In the WLC configuration, it can be divided into Radius and LDAP server authentication. Generally, the Radius server also needs to be linked with the AD database to realize user authentication. This document mainly describes the use of AD mobile directory as an LDAP server, which is directly linked with the WLC to implement Web login user authentication.)
