It's definitely cookie related. I just ran a test and upon clicking the logout button it will not do an automatic relogin, even if I restart the browser, until I remove the cookie. I cannot tell what the timeout is (cookie is all in code), so will have to run some tests to see if is expires in a few minutes or not.
 

It is indeed a 60 minute timeout before the cookie expires, which is the default setting defined in the web.config file...

    [authentication mode="Forms"]
      [forms name=".DOTNETNUKE" protection="All" timeout="60" cookieless="UseCookies" /]
    [/authentication]

I tested it and after 60 minutes it automatically logged me back in, even with the browser open.  So, it definitely is the cookie settings that are prohibiting the auto-relogin.

Is there documentation somewhere for this Extension?

I think I may have found the cause of the problem where users aren't automatically logged back in when their authentication cookie expires...

When a user logs in (either through DNN standard, windows manual or windowssignin.aspx) a cookie called ".DOTNETNUKE" is placed on their computer which is valid for the period specified in the web.config (default 60 minutes).

When a user is sent to windowssignin.aspx (either automatically by the authentication httpmodule or via a direct link) their windows credentials are requested and a cookie called "authentication.status.0" (0 since we are using portal ID=0) is written with a fixed timeout of one hour (AuthenticationController.vb line 535). Whilst this cookie exists the authentication module won't re-check windows credentials.

Now... why have we been having issues??? - I suppose there is a chance that some how the .DOTNETNUKE cookie is expiring before the authentication.status cookie, causing the user not to be logged in, but since the authentication.status cookie is still present their details aren't being re-checked.

Resolution.... I have set the timeout of the .DOTNETNUKE cookie to 61 minutes, so DNN should re-check windows credentials and update the .DOTNETNUKE cookie before the .DOTNETNUKE cookie expires, hopefully meaning we never have a situation where the sure is not logged in.

rvin2, are you putting the Domain name in front of your user names (if you haven't setup the default domain in the settings)? How long is your password. By default DNN expects it to be 7 characters long. You can change this in the web.config if your password length is shorter.

Yes, I also tried with or without domain name as everytime I tried to set the default domain in the settings page it doesn't seem to save the value. When i update the settings it gives me a successful message but when i return to the settings page the default domain is blank.

Password lenght is not a problem. Other asp.net applications with AD authentication in the same server have no issues.

Is there any other way to troublehsoot this issue? thanks again!

It seems that part of this thread fell off somewhere.  But rvin2 mentions that the default domain goes blank when the page is refreshed.  I'm having that same issue.  If I don't include the default domain, I can login fine.  And when I put the default domain in, I can't login at all, until I refresh that page and the default domain goes blank again.

I just downloaded DNN 5.4.1 today, and included was AD 5.0.2 so I'm running the latest versions.  Any ideas?  Where's that value stored and maybe I can go check to see if it's actually being written where it's supposed to.
