Description Rob Crittenden 2021-09-20 19:53:10 UTC

Description of problem:

tomcat 9.0.31.0 changed a connector attribute name from requiredSecret to secret. See https://tomcat.apache.org/connectors-doc/reference/workers.html

PKI unconditionally adds a new "secret" attribute to the connectors in server.xml regardless of version. I don't know what is adding it but it appears immediately after IPA installation is complete.

It looks like:

Some users of CentOS Stream 8 have reported authentication issues with the CA. They reported that removing the secret value and ensuring that requiredSecret matches the IPA configuration their CA works again.

For IPA the secret value need to match with the Apache configuration in /etc/ipa/ipa-pki-proxy.conf.

I haven't been able to reproduce in RHEL. Still, it is probably not valid to have both of these values set at the same time (and they appear to have differing secrets which I don't know is good or bad).

Not sure if this is related but there appears to have been an error in refactoring of commit https://github.com/dogtagpki/pki/commit/e70373ab131aba810f318c1d917896392b49ff4b

The version conditional was lost. The requiredSecret -> secret conversion should not be done in versions lower than 9.0.31.0.

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

pki-server-10.11.0-2.module+el8.5.0+12220+9cc212a8.noarch
ipa-server-4.9.6-4.module+el8.5.0+11912+1b4496cf.x86_64

Steps to Reproduce:
1. ipa-server-install <options>
2. pki-server upgrade
3. grep secret /etc/pki/pki-tomcat/server.xml

Comment 2 Endi Sukma Dewata 2021-10-01 16:42:59 UTC

Does CentOS Stream 8 work like RHEL 8? We only test against RHEL 8, and in RHEL 8 we assume there is only one Tomcat version per PKI version, so the version check was not necessary.

Instead of restoring the version check and having to support multiple Tomcat versions, can we simply require tomcat >= 9.0.31 and drop the requiredSecret?

Also note that the above commit doesn't change the upgrade behavior, i.e. replacing requiredSecret with secret, so I'm not sure how it ends up with both. Does IPA modify any of these attributes in server.xml?

Comment 3 Rob Crittenden 2021-10-01 18:18:12 UTC

I guess as long as that version of tomcat is available it's fine to set it as the minimum.

IPA also upgrades these settings in https://github.com/freeipa/freeipa/blob/master/ipaserver/install/dogtaginstance.py#L351 and it needs to keep the secrets in sync with its proxy configuration otherwise most CA requests fail with a 403.

I wasn't able to reproduce the behavior but at least three freeIPA users reported that they had both values set, with different secrets. IPA tries to honor existing secrets so its very possible it got confused by seeing both values, but like I said, I tried that and it worked for me.
