Problem accessing MS cube using different windows accounts

[globalbear]

I am trying to setup access to a MSAS 2005 cube with PowerPlay 7.4.

I have managed to setup a mdc file that points to the MS cube. If I browse the cube in the PowerPlay portal I get prompted for a login (cognos login page). I then enter my windows account and get access to the cube. If I try to enter a different windows account (that also has read access to the cube on the msas side) I get thrown back to the login page again without any error messages.

I have activated the powerplay logs and get this error message in the log file:

==== ppdsplOpen(Finance)

If I try my personal account (that works fine) I get this log:

Why can I not access the cube with a different windows account?
