Description Steve Grubb 2015-11-25 22:44:52 UTC
Description of problem:
Security Guidance advises people to not login via root. This is enforced in several places based on the security guides. However, it  looks like if someone/everyone gets locked out, it possibly requires a root login because the is the only account exempt from the lockout policy.

Most admins are members of the wheel group. Security Guidance typically asks admins to fix su or sudo to only allow wheel group members the ability to become root. I am wondering if the lockout exemptions for root should also be optionally extended to wheel group members so that we have a recovery method consistent with security guidance.

Comment 1 Tomas Mraz 2016-01-18 15:29:57 UTC
So what PAM modules are we talking here about?

pam_faillock is clearly one. Is there anything else?

Comment 2 Steve Grubb 2016-01-18 15:50:30 UTC
pam_faillock is the main one. I presume the pam_tally* modules are being deprecated at some future point.
