NAME

       tdbbackup - tool for backing up and for validating the integrity of samba .tdb files

SYNOPSIS

       tdbbackup [-s suffix] [-v] [-h]

DESCRIPTION

       This tool is part of the samba(1) suite.

       tdbbackup is a tool that may be used to backup samba .tdb files. This tool may also be used to verify the integrity of the .tdb files prior
       to samba startup or during normal operation. If it finds file damage and it finds a prior backup the backup file will be restored.

OPTIONS

       -h
           Get help information.

       -s suffix
           The -s option allows the adminisistrator to specify a file backup extension. This way it is possible to keep a history of tdb backup
           files by using a new suffix for each backup.

       -v
           The -v will check the database for damages (currupt data) which if detected causes the backup to be restored.

COMMANDS

       GENERAL INFORMATION

       The tdbbackup utility can safely be run at any time. It was designed so that it can be used at any time to validate the integrity of tdb
       files, even during Samba operation. Typical usage for the command will be:

       tdbbackup [-s suffix] *.tdb

       Before restarting samba the following command may be run to validate .tdb files:

       tdbbackup -v [-s suffix] *.tdb

       Samba .tdb files are stored in various locations, be sure to run backup all .tdb file on the system. Important files includes:

       o    secrets.tdb - usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba.

       o    passdb.tdb - usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba.

       o    *.tdb located in the /usr/local/samba/var directory or on some systems in the /var/cache or /var/lib/samba directories.

VERSION

       This man page is correct for version 3 of the Samba suite.

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.

       In contrast to read only backends like idmap_rid, it is an allocating backend: This means that it needs to allocate new user and group IDs
       in order to create new mappings. The allocator can be provided by the idmap_tdb backend itself or by any other allocating backend like
       idmap_ldap or idmap_tdb2. This is configured with the parameter idmap alloc backend.

       Note that in order for this (or any other allocating) backend to function at all, the default backend needs to be writeable. The ranges
       used for uid and gid allocation are the default ranges configured by "idmap uid" and "idmap gid".

       Furthermore, since there is only one global allocating backend responsible for all domains using writeable idmap backends, any explicitly
       configured domain with idmap backend tdb should have the same range as the default range, since it needs to use the global uid / gid
       allocator. See the example below.

IDMAP OPTIONS

       range = low - high
	   Defines the available matching uid and gid range for which the backend is authoritative. If the parameter is absent, Winbind fails over
	   to use the "idmap uid" and "idmap gid" options from smb.conf.

EXAMPLES

       This example shows how tdb is used as a the default idmap backend. It configures the idmap range through the global options for all domains
       encountered. This same range is used for uid/gid allocation.

		[global]
		# "idmap backend = tdb" is redundant here since it is the default
		idmap backend = tdb
		idmap uid = 1000000-2000000
		idmap gid = 1000000-2000000

       This (rather theoretical) example shows how tdb can be used as the allocating backend while ldap is the default backend used to store the
       mappings. It adds an explicit configuration for some domain DOM1, that uses the tdb idmap backend. Note that the same range as the default
       uid/gid range is used, since the allocator has to serve both the default backend and the explicitly configured domain DOM1.

		[global]
		idmap backend = ldap
		idmap uid = 1000000-2000000
		idmap gid = 1000000-2000000
		# use a different uid/gid allocator:
		idmap alloc backend = tdb

		idmap config DOM1 : backend = tdb
		idmap config DOM1 : range = 1000000-2000000
