Check if you have this enabled in radiusd.conf mschap { with_ntdomain_hack = yes } realm ntdomain { format = prefix delimiter = "\\" ignore_default = no ignore_null = no } and proxy.conf realm DEFAULT { strip } If you only have one domain this will work. If you have different domains you'll need to setup the individual realms. Sounds like in your case you don't though. Sergio Belkin wrote:

Please could you help me to find a fix?
