From 6b5acd9b0c8de965d9b815f8033a2bace9dd737d Mon Sep 17 00:00:00 2001

Subject: [PATCH] ipaclient: Defer creating the final krb5.conf on clients
A temporary krb5 configuration was used to join the domain in
ipaclient_join. After that the final krkb5 configuration was created
with enabled DNS discovery and used for the remainaing tasks, where also
a connection to the IPA API was done.
With several servers the DNS discovery could have picked up a different
server. If the client deployment was faster than the replication this
could have lead to an unknown host error.
The issue was seen in performance testing where many simultaneous client
enrollments have been done..
The goal is to keep server affinity as long as possible within the
deployment process:
The temporary krb5.conf that was used before in ipaclient_join was
pulled out into an own module. The generated temporary krb5.conf is now
used in ipaclient_join and also ipaclient_api.
The generation of the final krb5.conf is moved to the end of the
deployment process.
Same as: https://pagure.io/freeipa/issue/9228
The setup of certmonger has been pulled out of ipaclient_setup_nss and moved
to the end of the process after generating the final krb5.conf as it will
use t will only use /etc/krb5.conf.
Certificate issuance may fail during deployment due to using the final
krb5.conf, but certmonger will re-try the request in this case.
Same as: https://pagure.io/freeipa/issue/9246

Subject: [PATCH] ipaclient: ipaclient_setup_nss also needs krb_name parameter
With the fix to defer creating the final krb5.conf on clients a bug has
been introduced with ipaclient_setup_nss: The krb_name parameter that
points to the temporary krb5 configuration was not added to the module.
With a properly configured DNS (like for example IPA DNS) the krb TXT
records have been present in the DNS configuration. These have been used
automatically as a fallback and broke server affinity for the client.
Without the TXT records creating the IPA NSS database failed with
"Cannot find KDC for realm ..".
The krb_name parameter has been added to ipaclient_setup_nss and is also
properly set in tasks/install.yml.

been introduced with ipaclient_fix_ca: The krb_name parameter that
points to the temporary krb5 configuration was not added to the module
Without this the server affinity is broken for allow_repair and additionally
ipaclient_fix_ca could fail if krb5 configuration needs to be repraied
and also CA needs to be fixed.
The krb_name parameter has been added to ipaclient_fix_ca and is also
properly set in tasks/install.yml.

Subject: [PATCH] ipaclient: Fix allow_repair with removed krb5.conf and DNS
lookup
The test in ipaclient_test_keytab is at first trying to use an existing
krb5.conf to test if the host keytab can be used. With working DNS lookup
an absent krb5.conf is not reported as an error as DNS lookup is
silently used instead.
A temporary krb5.conf is now used in this test that forces to deactivate
DNS lookups and also to load /etc/krb5.conf. A missing krb5.conf is now
detected properly as the kinit call fails now properly. Thanks to Julien
Rische for this proposal.
ipaclient_test_keytab is now properly returning the state of usable or
not usable krb5.conf in krb5_conf_ok. This fixes the handling of this
case later on in the role.
