What Controls su Authentication post PAM?
by enorbet from LinuxQuestions.org on (#5H8DG)
Greetings
This doesn't have to with any bug but a Current system that suffered a botched upgrade-all (my bad). I've recovered all functionality but for one issue and I'm hoping it's an opportunity to learn something.
I can login as User and I can login as Root but "su" fails with the following error
Code:~$ su
Password:
su: Authentication service cannot retrieve authentication infoI see that /etc/pam.d/ contains a file for "su" but I don't see any glaring difference between it and the same file on other systems that work as expected.
How do I go about tracking what file is involved, what is not being satisfied to authenticate?
