idmap_tdb

## Name

idmap_tdb — Samba's idmap_tdb Backend for Winbind

## DESCRIPTION

The idmap_tdb plugin is the default backend used by winbindd for storing SID/uid/gid mapping tables and implements both the "idmap" and "idmap alloc" APIs.

## IDMAP OPTIONS

range = low - high

  Defines the available matching uid and gid range for which the backend is authoritative. Note that the range commonly matches the allocation range due to the fact that the same backend will store and retrieve SID/uid/gid mapping entries. If the parameter is absent, Winbind fail over to use the "idmap uid" and "idmap gid" options from smb.conf.

## IDMAP ALLOC OPTIONS

range = low - high

  Defines the available matching uid and gid range from which winbindd can allocate for users and groups. If the parameter is absent, Winbind fail over to use the "idmap uid" and "idmap gid" options from smb.conf.

## EXAMPLES

The following example is equivalent to the pre-3.0.25 default idmap configuration using the "idmap backend = tdb" setting.

    	[global]
    	    idmap domains = ALLDOMAINS
    	    idmap config ALLDOMAINS:default = yes
    	    idmap config ALLDOMAINS:backend = tdb
    	    idmap config ALLDOMAINS:range   = 10000 - 50000

    	    idmap alloc backend = tdb
    	    idmap alloc config:range = 10000 - 50000
