Somewhere I read that XOOPS will allow the user to be directed to their content without the need of going through the login screens. i.e. the user and pass handle is passed in with another application or url.

The reason why I am interested is that I would like to synchronise the XOOPS database with several external database user tables (create a site identifier and username automatically when user is created on an external database. ) in the external application the user has already authenticated and then links to a module in the XOOPS system (they should not need to re-enter their user/login to get connected).

If someone could point me in the right direction, I would appreciate it .

The BIG picture is that I have an application(web based) and it would be neat "if" the user had a problem that they may click a link on that application that will take them directly into XOOPS to review a FAQ, Raise a helpdesk ticket, or make comments on a forum, etc without having to authenticate every time they connect manually. (behind the scenes is what I am expecting or hoping)

Where can I find information relating to LDAP as this may be the answer I need to look at for accomplishing the task ?
