RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ 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?

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

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