1261530 – /etc/opendnssec is not writeable by ods-ksmutil running under ods user

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.

Comment 1 Martin Bašti 2015-09-09 14:25:18 UTC

there is missing write permission for group on /etc/opendnssec directory.

The daemon fails when executing external command under user ods:

The difference between Fedora and RHEL spec is this:
-%attr(0770,root,ods) %dir %{_sysconfdir}/opendnssec
+%attr(0750,root,ods) %dir %{_sysconfdir}/opendnssec

I.e. the filesystem permissions prevent the daemon running under ods user from writting to the directory.

This has to be fixed in opendnssec package.

Comment 4 Petr Spacek 2015-09-10 11:34:29 UTC

This bug has to be fixed otherwise the DNSSEC signing feature in FreeIPA will not work at all. Paul, can you get dev_ack for it?

Comment 6 Paul Wouters 2015-09-10 15:44:57 UTC

confirmed
