#19 Intermittent Login Failures
I'm seeing a number of "authentication failure" messages
appear in the logs and getting reports from a number of
users that are getting the login dialog erroneously.
This problem only appears to occur under load and
occurs irregularly. Some users do not hit this problem,
while others see it frequently. If the user closes their
browser and opens a new browser the problem is often
solved. Also, if they wait for the KeepAlive time to
expire, and press refresh, they are generally
authenticated correctly.
For users who are not logged onto the correct domain,
the password prompt is raised (which is correct), but
their authentication details are often refused. Again, if
the user then cancels the login dialog, waits for the
KeepAlive timeout to expire, and presses refresh, they
are typically allowed in.
I currently have the KeepAlive time set to 15 seconds.
I've done an strace of the process and found that the
authentication failures occur when getting SIGPIPE
(broken pipe) errors when trying to communicate with
the domain controller.
I have tried the reload patch but this doesn't seem to
help, nor does it prevent the login dialog if I sit there
pressing the refresh button quickly.
We're running:
Red Hat Linux 7.2
Apache Web Server 1.3.27-2
and are running against Win2K domain controllers.
I would appreciate any suggestions.

My remake fixes this problem. We had the exact same problem
you're having, but it works like a charm now :)

See http://coded.us for more information. I've still haven't
been able to contact the creators of mod_ntlm, so no

Try setting MaxKeepAliveConnections to zero. That is what
solved this for me.
