pam_sss - PAM module for SSSD
pam_sss.so [quiet] [forward_pass] [use_first_pass] [use_authtok] [retry=N]
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.
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.
MODULE TYPES PROVIDED
All module types (account, auth, password and session) are provided.
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.
