Fix Recommendation

Configure the AUTH control option is set to (OVERRIDE, ALLOVER) or (MERGE, ALLOVER). With (OVERRIDE, ALLOVER), TSS separately searches first the user, then profiles, and then the ALL record for its access authorization. With (MERGE, ALLOVER), TSS merges and searches the user and all profiles, and then the ALL record for its access authorization. Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option setting to AUTH(OVERRIDE, ALLOVER) or AUTH(MERGE, ALLOVER) and proceed with the change.
