EAP-MSCHAP v2 + LDAP: Identity does not match User-Name, setting from EAP Identity.

[Andras Dosztal]

Hi,

I've configured FreeRADIUS (version 1.1.7, supplied with SLES10) to  
authenticate from Novell eDirectory with LDAP. The problem is that I can't  
connect to the network when I check the "Automatically use my Windows  
logon name and password" on a WinXP client's PEAP properties. This is the  
output of radiusd -A -X:

The with_ntdomain_hack directive is set to "yes" in the preprocess and  
mschap modules of radiusd.conf. When I set it to "no" and uncheck the  
"Automatically use my Windows..." and enter the user's credentials in a  
pop-up box, it's working fine.
Could you guys help me with this problem? Thanks in advance.

Regards,
Andras
