sssd - System Security Services Daemon
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.
Please note that each SSSD service logs into its own log file. Also please note that enabling “debug_level” in the “[sssd]” section only enables debugging just for the sssd process itself, not for the responder or provider processes. The “debug_level” parameter should be added to all sections that you wish to produce debug logs from.
In addition to changing the log level in the config file using the “debug_level” parameter, which is persistent, but requires SSSD restart, it is also possible to change the debug level on the fly using the sss_debuglevel(8) tool.
Currently supported debug levels:
0, 0x0010: Fatal failures. Anything that would prevent SSSD from starting up or causes it to cease running.
1, 0x0020: Critical failures. An error that doesn't kill SSSD, but one that indicates that at least one major feature is not going to work properly.
2, 0x0040: Serious failures. An error announcing that a particular request or operation has failed.
3, 0x0080: Minor failures. These are the errors that would percolate down to cause the operation failure of 2.
4, 0x0100: Configuration settings.
5, 0x0200: Function data.
6, 0x0400: Trace messages for operation functions.
7, 0x1000: Trace messages for internal control functions.
8, 0x2000: Contents of function-internal variables that may be interesting.
9, 0x4000: Extremely low-level tracing information.
9, 0x20000: Performance and statistical data, please note that due to the way requests are processed internally the logged execution time of a request might be longer than it actually was.
10, 0x10000: Even more low-level libldb tracing information. Almost never really required.
To log required bitmask debug levels, simply add their numbers together as shown in following examples:
Example: To log fatal failures, critical failures, serious failures and function data use 0x0270.
Example: To log fatal failures, configuration settings, function data, trace messages for internal control functions use 0x1310.
Note: The bitmask format of debug levels was introduced in 1.7.0.
Default: 0x0070 (i.e. fatal, critical and serious failures; corresponds to setting 2 in decimal notation)
0: Disable timestamp in the debug messages
0: Disable microseconds in timestamp
stderr: Redirect debug messages to standard error output.
files: Redirect debug messages to the log files. By default, the log files are stored in /var/log/sssd and there are separate log files for every SSSD service and domain.
journald: Redirect debug messages to systemd-journald
Default: not set (fall back to journald if available, otherwise to stderr)
If the environment variable SSS_NSS_USE_MEMCACHE is set to "NO", client applications will not use the fast in-memory cache.
If the environment variable SSS_LOCKFREE is set to "NO", requests from multiple threads of a single application will be serialized.
