check your user account attributes "su" it should be set to true.

Check the root group membership definition.

I encountered this error once when the primary group
wasn't defined on the /etc/group.

: Hi,
: I did the following:

: $su root
: root's Password: ( I gave correct password )
: 3004-503 cannot set process credentials: No permission

: Can any one tell me what's wrong and what I shold do in order to login as root?

: TIA
