Description Scott Poore 2012-04-02 17:50:04 EDT
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):

How reproducible:

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 


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:

<title>500 Internal Server Error</title>
<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>
<address>Apache/2.2.15 (Red Hat) Server at storm.testrelm.com Port 443</address>

And we see AVCs:

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