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 Dmitri Pal 2011-06-13 16:12:36 UTC 
Reduce number of ports that CA is using. There are too many holes one needs to provide in the firewall for IPA to work.

See also the mail thread on the freeipa-users list:

https://www.redhat.com/archives/freeipa-users/2011-June/msg00100.html

Here is a follow up discussion on IRC:

<alee> simo: responded .. the error occurs before then - it looks like
his replica cannot resolve or contact the relevant port on the master
<simo> alee, I guess firewall then
<simo> this is one of the worst disadvantages of having a separate
instance for CS ...
<simo> alee, but wht do you need all those ports on a server anyway ?
<simo> alee, what are they used for ? why multiple ports and not simply
different URLs ?
<alee> simo: originally - the cs server ran with just a couple of ports
(secure and unsecure), but there was a customer request to separate
roles to different ports
<simo> rcrit, ^^ I think we will need to add a truckload of ports to the
documentation
<simo> rcrit, I think it is a *very* good idea that we decide to limit
CA replicas going forward as this is going to be a major issue in many
places
<alee> simo: so admin stuff happens on one port, agent stuff on another
port, ee stuff on another port
<simo> alee, ah the famous customer that gets everythnig they ask for
even when it makes no sense whatsoever? :-)
<alee> simo: yes well - money talks :/
<simo> alee, and this is now hardcoded that way ? It is not possible to
re-consolidate everything in one port ?
<simo> having to ask network admins to open that many ports is going to
have *a lot* of push back in most customer sites
<alee> simo: it is still possible to use a single port (secure and
unsecure) but we have not really tested that configuration well lately
<simo> even just the replication ports are going to be frowned on I
think :/
<simo> alee, is there any documentation on how to do that ?
<alee> simo: its not the standard config - but it is docuemnted in the
cs docs
<simo> alee, is it difficult to change the config to do that after
install ?
<alee> simo: you select that as an option during pkicreate
<simo> alee, yes but I need to find out if we can do that as an upgrade
option
<alee> simo: its much more difficult to change post-install .. ie, you
have to parse a server.xml file pretty much
<simo> sigh ...
<alee> but its possible
Comment 2 Dmitri Pal 2011-06-13 16:13:46 UTC 
This is something we need to align with IPA 2.2.

CAVEATS:
(1) fix 'base/selinux/src/pki.if' line to use subsystem variable rather than 'pki_ca_t'
(2) clone bug to provide 'proxy.conf' file for KRA, OCSP, and TKS subsystems

Comment 13 Jenny Severance 2011-10-17 16:43:01 UTC 
Can you please define what was changed? Steps to verify?
Thanks
Comment 14 Ade Lee 2011-10-26 18:13:17 UTC 
Jenny, 

It is now possible to run the CS behind a proxy apache server.  By default, this apache proxy server will serve pages on ports 443 and 80.

The CA continues to use the same ports - in fact an additional ajp port has been opened - but none of these ports need to be exposed outside of the local machine.

This is the current configuration in IPA.

To verify: 

0. Install httpd.  Start it and make sure you can get to the test page. 
1. Use pkicreate to create a CA instance.  Be sure to use the relevant proxy flags:

 [-enable_proxy]                            #enable proxy configuration
 [-ajp_port=<ajp_port>]                     #AJP port, default 9447
 [-proxy_secure_port=<proxy_secure_port>]   # Proxy secure port, 
                                            # default 443

 [-proxy_unsecure_port=<unsecure_port>]     # Proxy unsecure port,
                                            # default 80

3. Configure the CA, and restart it.

4. Configure httpd to be able to connect use https.  Use the CA to issue your server cert.  Confirm that you can connect to the apache proxy using https. 

5. Copy the /var/lib/<instance_name>/conf/proxy.conf file to /etc/httpd/conf.d and set permissions/ownership.  Also ensure that NSSRenegotiation is allowed and safe renegotiation is permitted.  (nss.conf)

6. Restart httpd.

7. You should be able to browse to the ca ee and agent pages through the proxy ports.

For example  (for standard ports): https://test.example.com/ca/ee/ca
                                   https://test.example.com/ca/agent/ca

and be able to submit cert requests and get certificates etc.  You should also be able to access the ca using the console - and be able to install other CS subsystems.

Note; Some operations may fail -- specifically when ee profiles that require client auth are submitted, and possibly renewal.  This is being investigated.

FWIW, ipa does all the setup for this - and this is how IPA currently runs.
Comment 15 Ade Lee 2011-10-26 18:14:25 UTC 
Jenny, 

So another way to verify this - is to confirm that all ipa functionality related to certs still works correctly.
Comment 16 Namita Soman 2011-11-07 15:50:29 UTC 
Kashyap is helping me with verifying this bug. Got to step 7, but the pages come up blank. He suspects -  the pki-ca in RHEL6 doesn't yet expose the profiles info. 

Needinfo - how to proceed?

steps taken to verify

Kashyap went through the steps above, while i watched, took notes, which i will attach here. also IPA certs tests are looking good. 
Verified using ipa-pki-common-theme-9.0.3-7.el6, ipa-pki-ca-theme-9.0.3-7.el6
