int MGOupdsuperuser (Admin *adm)
The MGOupdsuperuser() function updates an existing superuser record. Information is passed through adm. The required fields are:
adm.principal is the principal name. adm.comment is the comment field, used to state why the principal was added. You can only change the comment field. To change the principal field, you must insert a new record.
Returns the number of records updated upon success or -1 if an error occurred (in which case MGOerrno and MGOerrmsg are set appropriately).
