Hello,

I am trying to build my apache module which needs to carry out
authentication and authorization functions based on the value of a cookie.
To start with, I have just created a shell with the intent that I wanted the
functions for authentication and authorization being called.
However, it does not appear that these functions are being called. I have
pasted by configuration and code below.

When I try to access  http://localhost/test_rpc/ I get the login.html that
is defined in my ErrorDocument below.
But when I look in the log file, I see the following.
Since its looking for a userId, I am wondering if there is an error in my
configuration

[Sat Oct 01 16:37:29 2011] [debug] prefork.c(996): AcceptMutex: sysvsem
(default: sysvsem)
[Sat Oct 01 16:38:08 2011] [error] [client 127.0.0.1] access to
/test_rpc/header.jsp failed, reason: verification of user id '<null>' not
configured

Any guidance on what I am doing wrong would be greatly appreciate.

Regards
Suneet
