RE: Documenting / Managing iSeries security

I abhor supplemental groups.  Had a couple of problems with that:

1)  Someone started assigning a 'owner' profile as a supplemental group 
profile.  This 'owner' profile had the special authority of *ALLOBJ.  Thus 
all the users with this supplemental group had *ALLOBJ.
Cardinal rule #1-'Owner' profiles should not have any special authorities.

2)  Supplemental groups significantly increase the length of your SAVSYS. 
Increased ours from 4 minutes to 44 minutes.

3)  There is a limit to how many supplemental groups one user may be 
assigned to.  We were actually hitting this.

Better to use authorization lists wisely.
