IE security setings

We are in the process of rolling out Tessitura 11. All seems to be going well, until we get to reporting.

With the changes in version 11 it seems that we need to adjust security settings for our resident groups access for reports to run. Resident groups are not part of the center, so therefor they do not have the same security settings.

Our security settings are controlled by GPO. Can someone tell me what are the security settings in IE needed for reports to run?

Reporting works fine if user is a member of the Center, and has the Default Domain policy applied.
