Working with Global.asax

I have a problem related to the page authentication. . . i am trying to
implement the Windows authentication in the project,
I am using the LDAP services to fetch the details from the widows directory.
.. .

I mainly use the User.Identity.Name to fetch the user name and keep the
details in the session and passthrough where ever required

First Problem:
Even though the sessions are not expired the user is displayed with the
windows authentication form

Second Problem:
How to get the details of user along with the Groups Assigned to him

Third Problem:
When the sessions are expired, i need to know the situation that sessions
are expired

My main idea is first authentication from the Windows and then with the
database of mine and give him the permission> First Problem:

Can you rephrase? I don't follow what your question is.

Call the Win32 API LogonUser or use prorocol transition:

I'd suggest not using sessions. Instead cache the data in the ASP,NET data
cache. If the cache times out then just reload the cache. It avoids all sorts
of session issues.
