SSSD's idmap_sss Backend for Winbind


The idmap_sss module provides a way to call SSSD to map UIDs/GIDs and SIDs. No database is required in this case as the mapping is done by SSSD.

Idmap Options

range = low - high

Defines the available matching UID and GID range for which the backend is authoritative.


This example shows how to configure idmap_sss as the default mapping module.

security = ads

idmap config <AD-DOMAIN-SHORTNAME> : backend        = sss
idmap config <AD-DOMAIN-SHORTNAME> : range          = 200000-2147483647

idmap config * : backend        = tdb
idmap config * : range          = 100000-199999

Please replace <AD-DOMAIN-SHORTNAME> with the NetBIOS domain name of the AD domain. If multiple AD domains should be used each domain needs an idmap config line with backend = sss and a line with a suitable range.

Since Winbind requires a writeable default backend and idmap_sss is read-only the example includes backend = tdb as default.
