Hello all, I set a radius server for wifi authentication, I can log in wifi by username and password in radius server user file using mobile phone. Then, I need to use ldap server as the backend database for user authentication, I can use radtest on radius to connect with ldap server successfully. However I can not log in to wifi by the username and password stored in ldap server. As mschapv2 is not supported by ldap, so I use ttls as the default peap method. The ldap server will only give me the information about accept or reject, but it would not reply me with a password. If possible, can anyone tell me the authentication process between ldap server and radius server. All of the above are the problem what I encountered by now, can anyone help with this, this problem really drive crazy, Thanks. Best Regards Li
