* Group Name Attribute - Attribute to use to extract group name (i.e. cn).
Optional. If not set, the entire DN is used.
* Group Member Attribute - Attribute to use to define group membership
(i.e. member). Optional. If not set group membership will not be calculated
through the groups. Will rely on group member being defined through 'User Group
Name Attribute' if set.
Another option for the UserGroupProvider are composite implementations.
This means that multiple sources/implementations can be configured and
composed. For instance, an admin can configure users/groups to be loaded from a
file and an directory server. There are two composite implementations, one that
supports multiple UserGroupProviders and one that supports multiple
UserGroupProviders and a single configurable UserGroupProvider.
The CompositeUserGroupProvider will provide support for retrieving users
and groups from multiple sources.

Ah. Sorry your totally right. I forgot about those checks. They have been
in place for awhile. So that constraint shouldn't be unique to the composite
providers. Regardless, I will update the documentation accordingly. I suppose I
could remove those tests I referenced since they will never hit when running in
the app. However, they still ensure the order the providers are invoked so I'll
probably leave them in place. Anyways, thanks for confirming.
