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.

Description ilmostro7 2016-02-04 08:19:37 UTC 
Description of problem:
Decommissioning a system as the IPA Server(IdM) using `ipa-server-install --uninstall` and/or `ipa-server-install --uninstall -U` leaves residual IPA/IdM related files on system; e.g. during the installation, I presume the httpd.service file is copied into /etc/systemd/system/httpd.service and modified to suit the needs of the IPA server instance.  This is evident in bug 1044994.


Version-Release number of selected component (if applicable):

ipa-server-4.2.0-15.el7_2.3.x86_64

How reproducible:

Assuming user executes uninstall script as referenced in first line the `/etc/systemd/system/httpd.service` file is left in place with residual, irrelevant environment variables/links, rendering the Apache web server unable to start.

~~~
# cat /etc/systemd/system/httpd.service 
.include /usr/lib/systemd/system/httpd.service

[Service]
Environment=KRB5CCNAME=/var/run/httpd/ipa/krbcache/krb5ccache
Environment=KDCPROXY_CONFIG=/etc/ipa/kdcproxy/kdcproxy.conf
ExecStartPre=/usr/libexec/ipa/ipa-httpd-kdcproxy
ExecStopPost=-/usr/bin/kdestroy -A
~~~

Actual results:
