sssd 8 sssd System Security Services Daemon sssd options SSSD provides a set of daemons to manage access to remote directories and authentication mechanisms. It provides an NSS and PAM interface toward the system and a pluggable backend system to connect to multiple different account sources as well as D-Bus interface. It is also the basis to provide client auditing and policy services for projects like FreeIPA. It provides a more robust database to store local users as well as extended user data. -d,--debug-level LEVEL Debug level to run the daemon with. 0 is the default as well as the lowest allowed value, 10 is the most verbose mode. This setting overrides the settings from config file. This parameter implies -i. debug_timestamps (bool) Add a timestamp to the debug messages Default: false -f,--debug-to-files Send the debug output to files instead of stderr. By default, the log files are stored in /var/log/sssd and there are separate log files for every SSSD service and domain. -D,--daemon Become a daemon after starting up. -i,--interactive Run in the foreground, don't become a daemon. -c,--config Specify a non-default config file. The default is /etc/sssd/sssd.conf. For reference on the config file syntax and options, consult the sssd.conf 5 manual page. SIGTERM/SIGINT Informs the SSSD to gracefully terminate all of its child processes and then shut down the monitor. SIGHUP Tells the SSSD to stop writing to its current debug file descriptors and to close and reopen them. This is meant to facilitate log rolling with programs like logrotate. SIGUSR1 Tells the SSSD to simulate offline operation for one minute. This is mostly useful for testing purposes. SIGUSR2 Tells the SSSD to go online immediately. This is mostly useful for testing purposes. sssd.conf5 , sss_groupadd8 , sss_groupdel8 , sss_groupmod8 , sss_useradd8 , sss_userdel8 , sss_usermod8 .
