idmap_rfc2307 - Samba's idmap_rfc2307 Backend for Winbind
The idmap_rfc2307 plugin provides a way for winbind to read id mappings from records in an LDAP server as defined in RFC 2307. The LDAP server can be stand-alone or the LDAP server provided by the AD server. An AD server is always required to provide the mapping between name and SID, and the LDAP server is queried for the mapping between name and uid/gid. This module implements only the "idmap" API, and is READONLY.
Mappings must be provided in advance by the administrator by creating the user accounts in the Active Directory server and the posixAccount and posixGroup objects in the LDAP server. The names in the Active Directory server and in the LDAP server have to be the same.
This id mapping approach allows the reuse of existing LDAP authentication servers that store records in the RFC 2307 format.
When connecting to the LDAP server provided by an AD server, the parameter ldap ssl ads determines whether SSL should be used. When using a stand-alone LDAP server, ldap ssl applies.
range = low - high
ldap_server = <ad | stand-alone >
user_cn = <yes | no>
The following example shows how to retrieve id mappings from a stand-alone LDAP server. This example also shows how to leave a small non conflicting range for local id allocation that may be used in internal backends like BUILTIN.
[global] idmap config * : backend = tdb idmap config * : range = 1000000-1999999 idmap config DOMAIN : backend = rfc2307 idmap config DOMAIN : range = 2000000-2999999 idmap config DOMAIN : ldap_server = stand-alone idmap config DOMAIN : ldap_url = ldap://ldap1.example.com idmap config DOMAIN : ldap_user_dn = cn=ldapmanager,dc=example,dc=com idmap config DOMAIN : bind_path_user = ou=People,dc=example,dc=com idmap config DOMAIN : bind_path_group = ou=Group,dc=example,dc=com
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
