Re: Wierd permissions on user accounts


That is exactly what I tought would happen. These DENY rules are assigned
to user accounts when I created them...by default. When I create a new
account and look at the permissions. I have the following deny rules..

DENY - Everyone - Change Password - <not inherited> - This object only
DENY - Self - Change Password - <not inherited> - This object only

If I click the DEFAULT button in the Advance security settings on this NEW
user account I just created, these Deny rules are removed.

Why are the default permissions that are assigned to the object different
then the permissions assigned to the object after using the Default button?
