Authentication called 3 times in a "normal" navigation

See http://markmail.org/message/auxzq44jp5x3yqdw :

Thanks for the clarification. However, I have futher question about the connection. The following are the debug messages from log4j when a user did a single click on a normal navigation. There are basically 3 parts. 1st, user found 2nd, user object null (which is my main question) 3rd, getting the page comment

I assume after the first connection, users was authenticated. Why there was the 2nd connection with null object? I am using Enterprise LDAP, and not be able to go live into Production without clearing this issue. I have the Trace from LDAP side if that helps.

I am planning to go live the system in 2 weeks, so its fairly urgent to get this issue resolved please. Appreciate your thoughts.

Many Thanks
Art
