Description lizzha 2016-03-17 06:47:03 UTC

We're going to implement password policy in the on-demand Azure RHEL images, to align with the password policy from Azure portal.

Here're the rules
- The password must be between 6-72 characters long.
- The password must contain 3 of the following:
  a lowercase character
  an uppercase character
  a number
  a special character 

We come out the below solution, could you please help review?

Add following lines in /etc/security/pwquality.conf
minlen = 6
dcredit = 1
ucredit = 1
lcredit = 1
ocredit = 1
minclass = 3

Again as libpwquality calls cracklib the configuration needs to be similar to RHEL-6 - that means this is the proper configuration:

minlen = 6
dcredit = 0
ucredit = 0
lcredit = 0
ocredit = 0
minclass = 3
