It would be a bit surprising for ntlm_auth to take that long, unless 
your AD controllers are very heavily loaded or are very distant. It 
takes ~30 milliseconds to auth a user/challenge pair in our installation.

You could try restarting winbind - maybe it's gone crazy or eaten a load 
of RAM or something.

If it is ntlm_auth, upgrading FreeRadius probably won't help (unless you 
take advantage of the SSL session resumption available in later versions 
to avoid doing some of the auths on re-auth)
