pam tacacs fallback not working

[laminelaye]

hello i try to use pam_tacplus1.3.6 to authenticate users that try to connect to linux server using cisco ACS as a tacacs server . the authentication work fine if the tacacs server is alive but if all tacacs servers are dead i can't authentifiacte using my local account

this is my sshd config

auth sufficient pam_tacplus.so debug server=192.168.253.10 secret=natel221!
auth required pam_sepermit.so
auth include password-auth
account required pam_nologin.so
account sufficient pam_tacplus.so debug service=ppp protocol=lcp
account include password-auth
password include password-auth

pam_selinux.so close should be the first session rule

session required pam_selinux.so close
session required pam_loginuid.so
session optional pam_tacplus.so debug server=192.168.253.10 secret=natel221! service=ppp protocol=lcp

pam_selinux.so open should only be followed by sessions to be executed in the user context

session required pam_selinux.so open env_params
session optional pam_keyinit.so force revoke
session include password-auth
