Designate a new Administrator

I can't seem to recall how to designate a new Administrator for a NetWare 6.5, SP8 server. I first created a new user object and in the properties of my user object I set Security Equal to Me to the new user object. When I login to iManager as the new user there are no roles or tasks available. I know this probably isn't the best way to do this since if my user object gets deleted then this other user will lose rights.

I next tried, using iManager, Rights, Modify Trustees, selected the tree object, Add Trustee, selected the new user object and clicked Assign Rights. I gave the user Supervisor Rights for [All Attributes Rights] and [Entry Rights]. When I login to iManager as the user I still do not see any roles with this account.

Any advice appreciated.
