unable to restrict security access to all users of Appset

Hi All,

We recently installed BPC 5.1 in our company.

We tried creating one task profile for non admin users.

They should not be able to add/remove user, create/modify task/member access profiles.But unfortunatly, though I did not Include Define security task in there profile, every one is able to change the security settings. i.e every 1 is having manage security access.

Could you please help me.

Any help will be greatly Appreciated.
