When a Google user should be created, and it is detected that it already exists, the create() is changed to a modify(), but the attributes-to-be-set that were created for the create() operation are kept unmodified. This prevents migration scenarios, because the passwords of existing Google users are changed, when a UCS user is initially "connected" to an existing Google user. The 'password' attribute must be removed from the attribute list to prevent changing the password of an existing Google user.
should be still relevant for UCS 4.4
