Dotaz TMG and Sharepoint prompts for password 3 times

    I am having a strange issue and I am not sure where the problem is.  We are new to both TMG 2010 and Sharepoint 2010 so that makes it even worse.  We have a Sharepoint site and we are using TMG 2010 as the front-end.  When you first go to our portal and login, everything works great.  But if you go up and do a sign-in as a different user, you go back to the TMG login page.  (which is to be expected).  Now here is the issue.  At that page, your username is still there because most of us are saying it is a private computer but you have to type your password, hit enter, screen flashes, type password, hit enter, screen flashes, type your password, hit enter and then you get back into the portal.  I don't know if it is a delay between the TMG server and our domain controller or between the TMG and the Sharepoint server or between our domain controller and the Sharepoint server.  Our TMG server is in our DMZ with only one nic. So it is not part of the domain.  We have secure LDAP setup with a certifcate and everything.  Again, it is just when you do a sign in as a different user.  Has anyone else seen this?

    Thanks

    Update...This appears to be just a Sharepoint issue.  I hit the sharepoint server directly and bypassed the TMG.  I did a sign in as a different user and it does the same thing.  So I will move this post to the Sharepoint forum.

    I posted about this yesterday. This happens on all of our farms and only seems to be a problem if a user selects the option to sign in as a different user and if they try to log back in as themseleves. This is a problem when a users connection times out as they are prompted 3 times when they try to log back in. We noticed it first when going through TMG, but it seems to happen even if you hit the server directly. I haven't found a solution yet.
