188.8.131.52. Parameters for Configuring an LDAP Domain
Table 30.5. LDAP Domain Configuration Parameters
|ldap_uri||Gives a comma-separated list of the URIs of the LDAP servers to which SSSD will connect. The list is given in order of preference, so the first server in the list is tried first. Listing additional servers provides failover protection. This can be detected from the DNS SRV records if it is not given.|
|ldap_search_base||Gives the base DN to use for performing LDAP user operations.|
|ldap_tls_reqcert|| Specifies how to check for SSL server certificates in a TLS session. There are four options:
The default is hard.
|ldap_tls_cacert|| Gives the full path and file name to the file that contains the CA certificates for all of the CAs that SSSD recognizes. SSSD will accept any certificate issued by these CAs.
This uses the OpenLDAP system defaults if it is not given explicitly.
|ldap_referrals|| Sets whether SSSD will use LDAP referrals, meaning forwarding queries from one LDAP database to another. SSSD supports database-level and subtree referrals. For referrals within the same LDAP server, SSSD will adjust the DN of the entry being queried. For referrals that go to different LDAP servers, SSSD does an exact match on the DN. Setting this value to |
|ldap_schema|| Sets what version of schema to use when searching for user entries. This can be either |
In RFC 2307, group objects use a multi-valued attribute,
For example, with RFC 2307bis, all groups are returned when using nested groups or primary/secondary groups.
$ id uid=500(myserver) gid=500(myserver) groups=500(myserver),510(myothergroup)
If SSSD is using RFC 2307 schema, only the primary group is returned.
This setting only affects how SSSD determines the group members. It does not change the actual user data.
|ldap_search_timeout|| Sets the time, in seconds, that LDAP searches are allowed to run before they are canceled and cached results are returned. This defaults to five when the |
When an LDAP search times out, SSSD automatically switches to offline mode.
|ldap_network_timeout||Sets the time, in seconds, SSSD attempts to poll an LDAP server after a connection attempt fails. The default is six seconds.|
|ldap_opt_timeout||Sets the time, in seconds, to wait before aborting synchronous LDAP operations if no response is received from the server. This option also controls the timeout when communicating with the KDC in case of a SASL bind. The default is five seconds.|
