Defining the scope of fine-grained password policies
A PSO can be linked to a user (or inetOrgPerson) or a group object that is in the same
domain as the PSO: (…)
A new attribute named msDS-PSOApplied has been added to the user and group objects in
Windows Server 2008. The msDS-PSOApplied attribute contains a back-link to the PSO.
Because the msDSPSOApplied attribute has a back-link, a user or group can have multiple
PSOs applied to it.
As stated previously, in Windows Server 2008, a user or group can have multiple PSOs
applied to it since the msDS-PSOApplied attribute of the user and group objects has a backlink to the PSO.
