LDAP integration with intranet portal

[lamcro]

We have a home-grown intranet portal for a variety of uses (.NET web apps, reports made with Crystal Reports, etc.). This portal uses the same LDAP server the wiki uses. It runs on a Windows IIS server.

I would like to link some pages from the portal, it directly sends me to the portal's login page.

Any tips on what I should do to use the same login?

Take a look at the trusted authentication spec for a way to do SSO.

If you're using ldap, you can also considering using NTLM to automatically sign you into both systems.
