I've done a search of the forum and read the various posts I find, but I'm not seeing info specific to what I want to do, and I'm not sure if it's possible, or how to go about it. Hence the reason for my post.

Scenario: Users logon to a windows computer, authenticating against a Windows 2003 server, then then open a web browser and go to their bookmark "Zimbra Mail", their email appears on the screen.

So, what I'm looking at is a way for the currently logged on user to be logged into Zimbra automatically.

The problem as I see it is that the windows username is held in LDAP on the windows 2003 server, and the zimbra username and password is held in LDAP on the zimbra server.

Is it possible code a webpage, store it on the zimbra box so that when the page is opened, it finds out the windows username, discovers the zimbra user from that and logs them in?
