Hi,
=20
Environment: Apache/2.2.8 (Unix) DAV/2 mod_perl/2.0.4 Perl/v5.8.5
configured=20

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/Aut henNTLM.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
