Backend is located at http://www.domaina.com/system/

I created a user for Site B (doaminB.com) and gave him permission to access the backend, create posts, etc…

Now if I as admin hit the login as member button, I see the control panel the way I set it up and the way I expect it to be. 
when the user noe goes to http://www.domaina.com/system/ to login to siteB’s backend, he get’S an error message saying he does not have the required permissions.

Also ood is, that when I’m editing siteA in the backend, go to member group administration and hit the weblog asignment page, all I see is all weblog from siteB but none from siteA, even though the current site is set to A.

Mod Edit: Moved to the Technical Support forum.

Try setting up an admin.php in your SiteB folder and see if he can access that way.  Instructions here.

and again, thank you for your helpful hint. Worked like a charm.

Glad to hear it!
