AIX 5.x - Enforcing Password Complexity

This document explains how to require complex passwords on AIX 5.x systems.

Note: This documentation is intended as a reference for server administrators only. If you are not sure you are running a server, please check with your local IT staff before following these recommendations.

The following settings contained in /etc/security/user on an AIX 5.x system can be used to define system password policy:

  • minalpha = 4 <----sets the Minimum number of Alpha characters

  • minother = 1 <----sets the Minimum number of Other characters

  • minlen = 8 <----sets the Minimum length

  • mindiff = 4 <----sets the Minimum number of different characters

  • maxrepeats = 3 <--- A character may not repeat more than 3 times in a password
