An Interesting Problem with WordPress Integration

I have an interesting issue, and I’m wondering if anyone out there might have some ideas for me.

I’ve got a wordpress site setup (I’m building an Intranet with). I’ve got HESK integrated as well as http commander for a built-in helpdesk/kb and AD file share viewing capabilities. I’m using an active directory login pluggin to hook the site to AD authentication.

What I’d like to do is figure out how to make it a single sign-on. If a user is authenticated on the site with their AD creds, shouldn’t it be somewhat easy to pass that info to iframe for http commander so that they can view their file shares without having to login twice? and the HESK thing – that is a whole other user table in the database, so I have a bit of research to do on that.  My ultimate goal is to have one sign on for wordpress, and be done.

Any brilliant ideas?
