Hi Guys,

Iam using Samba Version 3.3.8-0.52.el5_5.2, (RPM)  and iam authenticating AD users with ntlm_auth (third party program using ntlm_auth to authenticate users through samba) . but my problem is how many concurrent requests can be handled by the ntlm_auth. I have seen lot of issues on squid proxy server (too many queued ntlm_auth requests and squid failures.)

Whats the maximum simultaneous connections it can handle ? (is it 256 ? ) how can I increase the limit ? and whats the maximum limit for that ?
