GroupsDict
A dictionary object containing the groups an account is a member of.
For each entry in the dictionary the key is the group's stable id, while the value is a dictionary object with 2 keys:
GAttrLongID - The long id of the group

An example is
groupsDict = {'stableid': {GAttrLongID: 'group1', GAttrSecurityDomain: 'domain1'}, 'stableid2': {GAttrLongID: 'group2'}}
