NAME
sss_override - create local overrides of user and group attributes
SYNOPSIS
sss_override COMMAND [options]
DESCRIPTION
sss_override enables to create a client-side view and allows to change selected values of specific user
and groups. This change takes effect only on local machine.
Overrides data are stored in the SSSD cache. If the cache is deleted, all local overrides are lost.
Please note that after the first override is created using any of the following user-add, group-add,
user-import or group-import command. SSSD needs to be restarted to take effect. sss_override prints
message when a restart is required.
NOTE: The options provided in this man page only work with “ldap” and “AD” “ id_provider”. IPA overrides
can be managed centrally on the IPA server.
AVAILABLE COMMANDS
Argument NAME is the name of original object in all commands. It is not possible to override uid or gid
to 0.
user-add NAME [-n,--name NAME] [-u,--uid UID] [-g,--gid GID] [-h,--home HOME] [-s,--shell SHELL]
[-c,--gecos GECOS] [-x,--certificate BASE64 ENCODED CERTIFICATE]
Override attributes of an user. Please be aware that calling this command will replace any previous
override for the (NAMEd) user.
user-del NAME
Remove user overrides. However be aware that overridden attributes might be returned from memory
cache. Please see SSSD option memcache_timeout for more details.
user-find [-d,--domain DOMAIN]
List all users with set overrides. If DOMAIN parameter is set, only users from the domain are listed.
user-show NAME
Show user overrides.
user-import FILE
Import user overrides from FILE. Data format is similar to standard passwd file. The format is:
original_name:name:uid:gid:gecos:home:shell:base64_encoded_certificate
where original_name is original name of the user whose attributes should be overridden. The rest of
fields correspond to new values. You can omit a value simply by leaving corresponding field empty.
Examples:
ckent:superman::::::
ckent@krypton.com::501:501:Superman:/home/earth:/bin/bash:
user-export FILE
Export all overridden attributes and store them in FILE. See user-import for data format.
group-add NAME [-n,--name NAME] [-g,--gid GID]
Override attributes of a group. Please be aware that calling this command will replace any previous
override for the (NAMEd) group.
group-del NAME
Remove group overrides. However be aware that overridden attributes might be returned from memory
cache. Please see SSSD option memcache_timeout for more details.
group-find [-d,--domain DOMAIN]
List all groups with set overrides. If DOMAIN parameter is set, only groups from the domain are
listed.
group-show NAME
Show group overrides.
group-import FILE
Import group overrides from FILE. Data format is similar to standard group file. The format is:
original_name:name:gid
where original_name is original name of the group whose attributes should be overridden. The rest of
fields correspond to new values. You can omit a value simply by leaving corresponding field empty.
Examples:
admins:administrators:
Domain Users:Users:501
group-export FILE
Export all overridden attributes and store them in FILE. See group-import for data format.
COMMON OPTIONS
Those options are available with all commands.
--debug LEVEL
SSSD supports two representations for specifying the debug level. The simplest is to specify a
decimal value from 0-9, which represents enabling that level and all lower-level debug messages. The
more comprehensive option is to specify a hexadecimal bitmask to enable or disable specific levels
(such as if you wish to suppress a level).
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.
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)
