We have 2 clients authenticating user one passes simply the uid (cburks) and users authenticate properly. The other client is passing username and realm (cburks@zhone.com), which fails. I have configured zhone.com realm in the proxy.conf file like this: realm zhone.com { type = radius authhost = LOCAL accthost = LOCAL } Radiusd.conf file has the following in the ldap section. filter = "(uid=%u)" Which works for username only and username + realm does not work if I switch to: filter = "(uid=%{Stripped-User-Name})" username + realm works and username alone fails. Is there a way different way to strip off the realm, so I can have both ways working? Thanks Corey When I run radiusd in debug I see that the realm is getting stripped but the username and relam are still being passed to LDAP.
