|
|---|
| 32 | .SH "DESCRIPTION"
|
|---|
| 33 | .PP
|
|---|
| 34 | 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\&.
|
|---|
| 35 | .PP
|
|---|
| 36 | 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\&.
|
|---|
| 37 | .PP
|
|---|
| 38 | This id mapping approach allows the reuse of existing LDAP authentication servers that store records in the RFC 2307 format\&.
|
|---|
| 39 | .PP
|
|---|
| 40 | When connecting to the LDAP server provided by an AD server, the parameter
|
|---|
| 41 | \m[blue]\fBldap ssl ads\fR\m[]
|
|---|
| 42 | determines whether SSL should be used\&. When using a stand\-alone LDAP server,
|
|---|
| 43 | \m[blue]\fBldap ssl\fR\m[]
|
|---|
| 44 | applies\&.

| 49 | Defines the available matching UID and GID range for which the backend is authoritative\&. Note that the range acts as a filter\&. If specified any UID or GID stored in AD that fall outside the range is ignored and the corresponding map is discarded\&. It is intended as a way to avoid accidental UID/GID overlaps between local and remotely defined IDs\&.

This allows using trust relationships while keeping all RFC 2307 records in one place\&. This parameter is optional, the default is to access the AD server in the current domain to query LDAP records\&.
