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-2012:0819 0 normal SHIPPED_LIVE ipa bug fix and enhancement update 2012-06-19 20:34:17 UTC

Description Scott Poore 2012-04-02 21:50:04 UTC 
Description of problem:

After upgrading from 2.1.3-9 in RHEL6.2 to 2.2.0-5, Web UI shows an Internal Server Error after login.  This was also seen on 2.1.3-9 -> 2.2.0-5 -> 2.2.0-7.  This appears related (at least somewhat) to bug 783592.   The SELinux httpd_manage_ipa boolean appears to be set to off after the upgrade.  Setting it to true/on fixes the problem.

Version-Release number of selected component (if applicable):
ipa-server-2.2.0-5.el6.x86_64
selinux-policy-3.7.19-142.el6.noarch


How reproducible:
very.  

Steps to Reproduce:
1.  <setup IPA server on RHEL6.2>
2.  kinit admin
3.  <install firefox and xauth if necessary>
4.  firefox https://$MASTER/ipa/ui
5.  <follow steps to configure firefox for single sign-on to IPA>

  
Actual results:

IPA returns an Internal Server Error in the browser.

6.  setsebool httpd_manage_ipa=on
7.  <select retry in browser>

IPA returns expected user page

Expected results:

Should not need to manually turn on the httpd_manage_ipa boolean.

Additional info:

Can check this entirely from the command line with this:

kinit admin 

jsonfile=/tmp/jsoninput

echo '{"method":"user_find","params":[[],{"sizelimit":0,"pkey_only":true}]}' > $jsonfile

sessionid=$(curl -v --negotiate -u: https://$MASTER/ipa/session/login_kerberos --cacert /etc/ipa/ca.crt 2>&1 |grep ipa_session 2>&1|sed 's/^.*ipa_session=\([0-Z]*\).*$/\1/')

curl  -H "Content-Type:application/json" -H "Referer: https://$MASTER/ipa/xml" -H "Accept:application/json"  -H "Accept-Language:en" --cacert /etc/ipa/ca.crt -d  @$jsonfile -X POST -b "ipa_session=$sessionid; httponly; Path=/ipa; secure" https://$MASTER/ipa/session/json 2>&1|grep "dn.*uid="

It will return html for the user list or an Internal Server Error page depending on how httpd_manage_ipa is set.

This is what the failure looks like:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>500 Internal Server Error</title>
</head><body>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error or
misconfiguration and was unable to complete
your request.</p>
<p>Please contact the server administrator,
 root@localhost and inform them of the time the error occurred,
and anything you might have done that may have
caused the error.</p>
<p>More information about this error may be available
in the server error log.</p>

And we see AVCs:

Comment 2 Martin Kosek 2012-04-03 07:54:18 UTC 
This SELinux boolean is set only for new installs. We need to set it for upgraded installs as well. I will open a ticket.
