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-timestamps=mode 1: Add a timestamp to the debug messages 0: Disable timestamp in the debug messages Default: 1 --debug-microseconds=mode 1: Add microseconds to the timestamp in debug messages 0: Disable microseconds in timestamp Default: 0 -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. --version Print version number and exit. 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. Environment variable SSS_NSS_USE_MEMCACHE If the environment variable SSS_NSS_USE_MEMCACHE is set to "NO", client applications will not use the fast in-memory cache. Amount of time SSSD spends in offline mode When SSSD switches to offline mode, the amount of time before it tries to go back online will increase based upon the time spent disconnected. This value is in seconds and calculated by the following: 60 + random_offset The random offset can increment up to 30 seconds. After each unsuccessful attempt to go online, the new interval is recalculated by the following: new_interval = old_interval*2 + random_offset Note that the maximum length of each interval is currently limited to one hour. If the calculated length of new_interval is greater than an hour, it will be forced to one hour.
