SSSD The SSSD upstream - http://fedorahosted.org/sssd pam_sss 8 pam_sss PAM module for SSSD pam_sss.so forward_pass use_first_pass use_authtok 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. 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. 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 setlocale3 . 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 permisssions. These files are searched in the directory /etc/sssd/customize/DOMAIN_NAME/. If no matching file is present a generic message is displayed. sssd.conf8
