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.

Red Hat Product Errata RHBA-2016:2471 0 normal SHIPPED_LIVE slapi-nis bug fix and enhancement update 2016-11-03 14:07:19 UTC

Description Martin Kosek 2014-04-04 06:40:48 UTC 
Description of problem:

FreeIPA uses slapi-nis compat tree so that the legacy hosts (without recent SSSD) can be configured to use LDAP authentication to authenticate IPA or AD users from trusted AD domains:

​http://www.freeipa.org/page/V3/Serving_legacy_clients_for_trusts

Password change should work both for IPA clients and AD clients. As we have enough attributes in the synthesized entry to distinguish IPA user from an AD user, we can try to add password modify callback that uses PAM stack. It doesn't need pam_passthru.

Comment 2 RHEL Program Management 2014-04-12 05:47:30 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 5 Alexander Bokovoy 2016-07-21 12:37:16 UTC 
This bug is fixed in slapi-nis 0.56.0. The rebase to slapi-nis 0.56.0 is tracked with bug #1292148.
Comment 6 Martin Kosek 2016-07-21 13:26:01 UTC 
Alexander, while you are right that this will be delivered with the rebase, it is an RFE that needs to go through the full Bug life-cycle, including a QE verification.

Moving to MODIFIED.
