Hoping someone can shed some light on the following:

I have an application (IBM Cognos TM1) that will not work for any computer in the DSFW domain. The only exception to this is a domain administrator. If I remove the computer from the domain, login to eDirectory using the Novell Client, the application works fine. IBM support believe there is a trust or delegation issue with the domain.
When I use Active Directory Users and Computers to look at the security of the windows server in the domain that hosts the application, all my security options are greyed out. I was hoping to give a test user elevated security to test further.
Has any come across this issue? Should I be able to change the security from here or should it be done another way.

Any help would be greatly appreciated.
