2023-12-08login: T4943: use pam-auth-update to enable/disable Google authenticatorChristian Breunig
The initial version always enabled Google authenticator (2FA/MFA) support by hardcoding the PAM module for sshd and login. This change only enables the PAM module on demand if any use has 2FA/MFA configured. Enabling the module is done system wide via pam-auth-update by using a predefined template. Can be tested using: set system login user vyos authentication plaintext-password vyos set system login user vyos authentication otp key 'QY735IG5HDHBFHS5W7Y2A4EM274SMT3O' See https://docs.vyos.io/en/latest/configuration/system/login.html for additional details. (cherry picked from commit e134dc4171b051d0f98c7151ef32a347bc4f87e2)
