# idmapwb(8)

winbind ID mapping plugin for cifs-utils

## Name

idmapwb.so - winbind ID mapping plugin for cifs-utils

## DESCRIPTION

This plugin allows the utilities in cifs-utils to work in conjuction with the winbind facility of Samba suite. It handles several functions including mapping UID and GID to SIDs and vice versa.

Utilities are usually configured to use the correct plugin by creating a symlink at */etc/cifs-utils/idmap-plugin* that points to the correct plugin that you wish to use.

This plugin requires that [winbindd(8)](/winbindd/8.md) be properly configured and running.
