Doc Text:
Cause: The new samba-3.6 release changed the way the idmap range for mapping users from the windows active directory to the system uids and gids. Consequence: Authconfig was no longer properly configuring the idmap range in smb.conf when --smbidmapuid and --smbidmapgid options were used. Fix: Authconfig was improved to properly use the new syntax of the idmap range configuration that is supported in samba 3.6. Result: The idmap range is properly configured if authconfig is used.

Description Tomas Mraz 2012-10-02 09:11:16 UTC 
+++ This bug was initially created as a clone of Bug #850824 +++

Description of problem:

In Samba 3.6 the id mapping configuration has been changed and simplified. See the release notes:

https://www.samba.org/samba/history/samba-3.6.0.html

and the smb.conf and idmap manpages.

Example:
        workgroup = LEVEL1
        realm = LEVEL1.DISCWORLD.SITE
        security = ads

        # v3.6 common id range
        passdb backend = tdbsam
        idmap config * : range = 1000000-1999999

        # Winbind domain idmap
        idmap config LEVEL1 : backend = rid
        idmap config LEVEL1 : range = 100000000-199999999

The same applies to RHEL 6.4, RHEL 7.0 and Fedora. Should I open a bug for each or will you just clone this bug?

--- Additional comment from tmraz on 2012-08-27 16:55:35 CEST ---

Is the new samba completely backwards incompatible with the old settings?

--- Additional comment from asn on 2012-08-27 17:25:27 CEST ---

No, the old idmap settings will not work anymore. You NEED to change them!
