Hi All, I am seeing some performance challenges with ntlm_auth (Currently running 3.0.15). My setup is pretty non-standard so I will apologise for this beforehand. But my hands are tied. Our mschap module actually calls a shell script which than calls ntlm_auth (we actually need to perform an ldap lookup before obtaining the samaccount name to pass to ntlm_auth), as expected this throws up some challenges under load. What I would like to know if its possible to do anything to improve performance under this circumstances. I know the direct winbind mode would have been great but the ldap lookup is critical for things to work our end. Mr Google returned some suggestions that their was an option to run ntlm_auth as a connection pool , is it still there / was it dropped in favour of direct winbind connectivity. Any suggestions welcome. Many Thanks Arnab
