Question about Group Mapping

HI

Our previous IM administrator set up our Wildfire admin console and he is no longer with the company. I am trying to add another security group to have access to use our IM client but I am not sure how to add another search item to the group filter he has setup.

He has it set to this:

(objectClass=group)(cn=it)

is there a way to add another filter? I want to add IM but still need IT to be there.

This is located under Server Settings> Profile Settings and then Group Mapping

Any advice would be greatly appreciated.

Thank you
