NAME

       pam_sss - PAM module for SSSD

SYNOPSIS

       pam_sss.so [quiet] [forward_pass] [use_first_pass] [use_authtok] [retry=N]
                  [ignore_unknown_user] [ignore_authinfo_unavail]

DESCRIPTION

       pam_sss.so is the PAM interface to the System Security Services daemon (SSSD). Errors and
       results are logged through syslog(3) with the LOG_AUTHPRIV facility.

OPTIONS

       quiet
           Suppress log messages for unknown users.

       forward_pass
           If forward_pass is set the entered password is put on the stack for other PAM modules
           to use.

       use_first_pass
           The argument use_first_pass forces the module to use a previous stacked modules
           password and will never prompt the user - if no password is available or the password
           is not appropriate, the user will be denied access.

       use_authtok
           When password changing enforce the module to set the new password to the one provided
           by a previously stacked password module.

       retry=N
           If specified the user is asked another N times for a password if authentication fails.
           Default is 0.

           Please note that this option might not work as expected if the application calling PAM
           handles the user dialog on its own. A typical example is sshd with
           PasswordAuthentication.

       ignore_unknown_user
           If this option is specified and the user does not exist, the PAM module will return
           PAM_IGNORE. This causes the PAM framework to ignore this module.

       ignore_authinfo_unavail
           Specifies that the PAM module should return PAM_IGNORE if it cannot contact the SSSD
           daemon. This causes the PAM framework to ignore this module.

MODULE TYPES PROVIDED

       All module types (account, auth, password and session) are provided.

FILES

       If a password reset by root fails, because the corresponding SSSD provider does not
       support password resets, an individual message can be displayed. This message can e.g.
       contain instructions about how to reset a password.

       The message is read from the file pam_sss_pw_reset_message.LOC where LOC stands for a
       locale string returned by setlocale(3). If there is no matching file the content of
       pam_sss_pw_reset_message.txt is displayed. Root must be the owner of the files and only
       root may have read and write permissions while all other users must have only read
       permissions.

       These files are searched in the directory /etc/sssd/customize/DOMAIN_NAME/. If no matching
       file is present a generic message is displayed.
