If the /var/log/lastlog file does not contain any old entries for the user, indicate that the user has never previously logged in with
a welcome message.
nodate
Don't display the date of the last login.
noterm
Don't display the terminal name on which the last login was attempted.
nohost
Don't indicate from which host the last login was attempted.
nowtmp
Don't update the wtmp entry.
noupdate
Don't update any file.
showfailed
Display number of failed login attempts and the date of the last failed attempt from btmp. The date is not displayed when nodate is
specified.
MODULE TYPES PROVIDED
Only the session module type is provided.
RETURN VALUES
PAM_SUCCESS
Everything was successful.
PAM_SERVICE_ERR
Internal service module error.
PAM_USER_UNKNOWN
User not known.
