Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Bug 1580281

Summary: Samba can not register sss idmap module because it's using an outdated SMB_IDMAP_INTERFACE_VERSION [rhel-7.5.z]

Fixed In Version: sssd-1.16.0-19.el7_5.3 Doc Type: Bug Fix
Doc Text:
Previously, the new Samba version in Red Hat Enterprise Linux 7.5 used a newer version of the idmap plug-in interface and SSSD still provided a plug-in with an older version. If Samba was configured to use SSSD's idmap plug-in, smdb and winbind services failed to start due to the version mismatch. With this update, SSSD provides a plug-in with a matching version. As a result, smdb and winbind run as expected.

Steps:
1. Join RHEL7.5 system to windows AD domain using below command

realm join -v TESTRELM.TEST --membership-software=samba

2. Configure smb.conf as below 

cat /etc/samba/smb.conf


[global]
        workgroup = TESTRELM
        realm = TESTRELM.TEST
        security = ads

        idmap config * : range   = 200000-2147483647
        log level = 9

3. restart winbind 

$ systemctl restart winbind

4. Run wbinfo

[root@host-8-242-110 sssd]# wbinfo -i TESTRELM\\administrator
TESTRELM\administrator:*:1507800500:1507800513::/home/TESTRELM/administrator:/bin/false
