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.

Fixed In Version: Doc Type: Bug Fix
Doc Text:
A previously updated version of slapi-nis introduced incompatibility of the slapi-nis external group-membership with the System Security Services Daemons (SSSD) default_domain_suffix option. As a consequence, the IPA compat-tree got inaccessible because external members of IPA groups could not be resolved during the initialization, and slapi-nis fails to start. A patch has been applied to fix the schema compatibility plug-in to work with SSSD, and slapi-nis is now compatible with the SSSD default_domain_suffix parameter.

# rpm -qa slapi-nis* ipa-server
ipa-server-4.2.0-15.el7_2.18.x86_64
slapi-nis-0.54-11.el7_2.x86_64

Step 1: configured ipa with AD  
Step 2: added default_domain_suffix = ad.domain in /etc/sssd/sssd.conf
Step 3: restart ipa server(ipactl restart)

Got expected output ('schema-compat-plugin - Finished plugin initialization.') in /var/log/dirsrv/slapd-HTESTRELM-TEST/errors

Comment 7 Varun Mylaraiah 2016-07-14 17:14:35 UTC 
Sorry, I forgot to mention one more step in comment6 "#service sssd restart"

Steps to verify
Step 1: configured ipa with AD  
Step 2: added default_domain_suffix = ad.domain in /etc/sssd/sssd.conf
Step 3: Restart sssd (#service sssd restart)
Step 4: restart ipa server(ipactl restart)
