I'm new to FreeRadius and trying to setup the server to authenticate using LDAP. I'm having some problem and hope to get some help from the list. I'm trying to setup AP->FR->LDAP. Both FreeRadius and LDAP are new installation on CentOS. I tried to follow the installation for FR and test each steps. test accounts are created in both user file and LDAP database. radtest are successful with both accounts. The problem is when I try to authenticate through AP. The debug log shows Failed to authenticate the user. here is the log file. # Executing section authorize from file /etc/raddb/sites-enabled/inner-tunnel +- entering group authorize {...} ++[chap] returns noop [mschap] Found MS-CHAP attributes.
