removing domain data from user name

[Yedidia Klein]

Hello list,


I'm using freeradius server as a radius server that forward the auth to 
an LDAP server,

on a RH enterprise system (freeradius-1.0.1-1.1.RHEL3)

I want one of my service providers to authenticate against this radius,

After enabling some debug option I found that it sends me the users in 
the form of user at domain.tld, that (of course) my ldap don't know and 
refuse to auth.

Is there a way on freeradius to pass to the ldap server only the left 
site of the @ sign ?


I tried to use "with_ntdomain_hack = yes" in my ldap section on 
radiusd.conf  w/o success.


thanks,
