This implies that by default, if TACACS is configured properly and it reported auth_err, then don't try fail through to traditional unix authentication through /etc/passwd. If this failthrough is intended, make it explicit through "sudo config aaa authentication failthrough enable" Removed an unused variable "aaa.fallback" Tested manually. Note the presence of 'auth_err=die' in all cases except when failthrough is explicitly enabled. admin@str-s6000-acs-13:~$ sudo config aaa authentication failthrough default; date Wed Apr 3 23:05:18 UTC 2019 admin@str-s6000-acs-13:~$ ls -lrt /etc/pam.d/common-auth-sonic ; grep 123 /etc/pam.d/common-auth-sonic -rw-r--r-- 1 root root 1316 Apr 3 23:05 /etc/pam.d/common-auth-sonic auth [success=done new_authtok_reqd=done default=ignore auth_err=die] pam_tacplus.so server=100.127.20.22:49 secret=testing123 login=login timeout=5 try_first_pass auth [success=done new_authtok_reqd=done default=ignore auth_err=die] pam_tacplus.so server=100.127.20.21:49 secret=testing123 login=login timeout=5 try_first_pass admin@str-s6000-acs-13:~$ sudo config aaa authentication failthrough enable; date ; h4 "AAA|authentication" Wed Apr 3 23:06:37 UTC 2019 admin@str-s6000-acs-13:~$ ls -lrt /etc/pam.d/common-auth-sonic ; grep 123 /etc/pam.d/common-auth-sonic -rw-r--r-- 1 root root 1294 Apr 3 23:06 /etc/pam.d/common-auth-sonic auth [success=done new_authtok_reqd=done default=ignore] pam_tacplus.so server=100.127.20.22:49 secret=testing123 login=login timeout=5 try_first_pass auth [success=done new_authtok_reqd=done default=ignore] pam_tacplus.so server=100.127.20.21:49 secret=testing123 login=login timeout=5 try_first_pass admin@str-s6000-acs-13:~$ sudo config aaa authentication failthrough disable; date ; h4 "AAA|authentication" Wed Apr 3 23:07:09 UTC 2019 admin@str-s6000-acs-13:~$ ls -lrt /etc/pam.d/common-auth-sonic ; grep 123 /etc/pam.d/common-auth-sonic -rw-r--r-- 1 root root 1321 Apr 3 23:07 /etc/pam.d/common-auth-sonic auth [success=done new_authtok_reqd=done default=ignore auth_err=die] pam_tacplus.so server=100.127.20.22:49 secret=testing123 login=login timeout=5 try_first_pass auth [success=done new_authtok_reqd=done default=ignore auth_err=die] pam_tacplus.so server=100.127.20.21:49 secret=testing123 login=login timeout=5 try_first_pass

There was a problem hiding this comment.
why change fallback as well? is fallback same as failthrough?
There was a problem hiding this comment.
No.
fallback is an unused variable. Just house cleaning.

* In sync with our latest change, where we default failthrough to be False. Reference: Pull request sonic-net#2746 * Loading minigraph, flushes DB, which is not sent as updates to hostcfgd. So stop hostcfgd before load and restart after load, to be able to act in sync with updated CONFIG-DB.

Tested manually. Note the presence of 'auth_err=die' in all cases except when failthrough is explicitly enabled.
