Hi YuNing,

The Abstract policy authorizer delegates the updateGroup action to doUpdateGroup, which is
implemented by the extending concrete class. I'm not sure where you are seeing that it checks
for the absence of the group, but there is an addGroup method for adding a new group.

"AbstractPolicyBasedAuthorizer", I found there is no method to add a user to an existing group.
I noticed there is an "updateGroup" method ,which i don't think can be used to add users to
existing group, because it checks the input group to make sure it didn't exist.
