iLO 2 & AD integration only working with 'Administrators' group.

[BDay]

iLO 2 w/1.78 firmware on DL360s and DL380s.

I have AD integration (non-HP Schema) working, but it only works if I use;

CN=Administrators,CN=Builtin,DC=domain,DC=com

...for the 'Administrators' Group Account within iLO 2. I'm not a member of this group directly, but am through a nested group.

If If I try to configure any other AD group (including the group nested within the Administrators group) I get the reponse;

Cause: Authenticated; Management Processor Login is not authorized.

Has anyone stumbled on this before?

Just found the iLO board, sorry for posting this here.
