PAM File Modification for Google Authenticator
1
i use the google authenticator for the ssh authentication, but i use a publickey + authenticator or a password + authenticator (when no publickey is defined it should be ask only for password, but i don't know how i can setup this.)
My sshd_config file (edits):
UsePAM Yes
AuthenticationMethods publickey,keyboard-interactive password,keyboard-interactive
and my PAM file:
#%PAM-1.0
auth required pam_sepermit.so
#auth substack password-auth
auth include postlogin
# Used with polkit to reauthorize users in remote sessions
-auth optional pam_reauthorize.so prepare
account required pam_nologin.so
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
# 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 required pam_namespace.so
session optional pam_keyinit.so force revoke
session include password-auth
session include postlogin
# Used with polkit to reauthorize users in remote sessions
#-session optional pam_reauthorize.so prepare
#auth [success=done new_authtok_reqd=done default=die] required
pam_google_authenticator.so nullok
auth sufficient pam_google_authenticator.so
auth required pam_unix.so no_warn try_fist_pass
It is working perfectly in normal login, but i use netbeans in development and in ssh mode - it is able to login successfully with ssh without a correct password or certificate in mode: keyboard-interactive (also the authentificator code)
