Hi, Environment: Apache/2.2.8 (Unix) DAV/2 mod_perl/2.0.4 Perl/v5.8.5 configured I'm trying to use Apache2-AuthenNTLM-0.02 for doing NTLM authentication. It works fine in normal scenarios. But if there are more than 2 requests come at the same time, I see the following error in Apahe error log file and it prompts for username / password. "SMB Server connection not open in state 3" As per the document (http://search.cpan.org/~speeves/Apache2-AuthenNTLM-0.02/AuthenNTLM.pm), i enabled serialization to solve the above issue (set ntlmsemkey value to "23754"). But now Apache is hanging after serving couple of requests. Am i missing something? what is the right value for ntlmsemkey? Any help? Thanks Subbaiah
