Ticket #48943 - When fine-grained policy is applied, a sub-tree has a priority over a user while changing password
Description: If the user entry has a pwdpolicysubentry, the configuration
in the pwpolicy should be the strongest and respected. If the entry does
not have it, it retrieves the pwpolicy from the CoS Cache, which is the
current behaviour.
