Description:  

By default, when a Peer Group is created that allows for password-authentication (or the password for such
a Group is changed), Peer Grouping validates that the password meets the password complexity
requirements for the local system.  Thus, it will not allow any passwords to be used for a Peer Group that are
weaker than what would be allowed for a login password.

This setting controls this validation behavior.  If set to 1, then this validation will not be performed and any
password will be allowed.  If set to 0, the validation will be performed..

Supported on: At least Windows Vista
