Description of problem: The next version of SSSD will be able to prompt users with 2-Factor-Authentication (2FA) separately for the two factors. This way the first factor (long term password) can be used e.g. to unlock the users keyring or for offline authentication. With the current configuration pam_unix will always prompt the user for a password. Letting SSSD ask users of 2FA again for the password will lead to a bad user experience. Letting SSSD only ask for the second factor will make it hard for applications like gdm to show specific 2FA dialogs. It would be best if pam_unix would only ask for password for local users and let SSSD prompt SSSD users. To achieve this pam_localuser could be added to the PAM configuration like in the following example: auth required pam_env.so auth sufficient pam_fprintd.so auth [default=1 success=ok] pam_localuser.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 1000 quiet_success auth sufficient pam_sss.so forward_pass auth required pam_deny.so To allow to configure the old version without pam_localuser as well the new line should only be added if --enableforcelegacy is not set.
I'd be happy to help here. Please tell me if you want me to provide a patch or if I shall test patches.

Please find attached a patch which adds a new option --enableSSSDAuthPrompting which adds the pam_localuser line and changes the option of pam_sss to forward_pass in the auth section if SSSD authentication is enabled (explicit or implicit). Since with this approach no existing behavior is changed and the new behavior must be enabled explicitly (e.g. by ipa-client-install) I would like to ask you if you can consider to include the patch in the Fedora 22 version of authconfig.
