Identity Mapping Back Ends

Supported ID Mapping Back Ends

Samba provides the following ID mapping back ends:

• idmap config ad (RFC2307)
• idmap config rid
• idmap config autorid
• idmap config hash
• idmap config ldap
• idmap config nss

Using ID Mapping Back Ends on a Samba AD DC

For setting up Winbindd a Samba Active Directory (AD) domain controller (DC), see Configuring Winbindd on a Samba AD DC.

ID mapping back ends are not supported in the smb.conf file on a Samba AD DC. For details, see Failure to Access Shares on Domain Controllers If idmap config Parameters Set in the smb.conf File.

On a Samba 4.6.x AD DC, the testparm utility displays ERROR: Invalid idmap range for domain *! You can safely ignore this, For details, see Bug #12629.
