Hi.  I'm having an issue with v5.0.3 (and also v5.0.2) of the AD auth module in DNN v5.6.2.  I can successfully login as an AD user.  But, depending on which AD user I login as, I very often get kicked out (redirected to login.aspx?returnpath=blah+blah)

I can make it happen pretty consistently.  After logging in, I click on a link to a custom page we have made.  It's basically an iframe, with a aspnet app inside it.  If I attempt to do anything on that page which involves a postback, I will get sent back to login.aspx?... and all page data is lost.  Also, if I just click the same link to get to this custom page, I will be redirected to login.aspx.  It does not happen for all AD accounts, only one that I've narrowed down so far.  The account is basically just a dupe of my own account (my account works, the dupe doesn't).  It also seems to happen for many of our custom pages, but also on standard DNN pages; but it is less consistently troublesome on std pages.  Btw, theres nothing about AD auth in these particular custom pages.

The strange thing about this is that we have 2 separate portals set up on the same box, with the same db backend.  They both have this same custom page link.  But it only happens on one of our portals, not the other one.  One portal never seems to have this issue; the other portal can't seem to get away from it.



I tried searching through the forums, and I may not be phrasing my searches well.  The closest issue I can find is from a few years back, and the resolution involved lowercase'ing both sides of a string comparison somewhere.  But, near as I can tell, that doesn't seem to be the problem here.  I even tried updating the users and aspnet_users tables to all lowercase, and making sure to login with a lowercase username, but that doesn't seem to help either.  can someone help me out here?

actually no.  its definitely not a timeout.  the issue can come up within 60 seconds.  when i test out this issue, i just click on a link.  wait for it to load.  click the same link, and bam, i'm logged out.

Did you ever resolve this? I have a related issue. iframe in custom module breaks ad authentication and user is logged out.
