addGroup creates a group but converts the specified name to lowercase. However when accessing the group via userAccessor getGroup does NOT convert the specified groupname to lowercase. This means that if a remote client does addGroup("valid-token", "DUMMY-admin") the group will be created in confluence as dummy-admin. If the remote client does addUserToGroup("valid-token", "jim", "DUMMY-admin") you get a remote exception saying that the group does NOT EXIST because it is stored a dummy-admin. The problem is explained above.

Thanks.
