The client installer code can be called in 3 different ways:
- from ipa-client-install CLI
- from ipa-replica-install CLI if the client is not already installed
- from ipa-server-install
In the last case, the client installer is called with
options.on_master=True
As a result, it's skipping the part that is creating the krb5
configuration:
if not options.on_master:
nolog = tuple()
configure_krb5_conf(...)
The configure_krb5_conf method is the place where the krb5.conf file is
backup'ed with the extention ".ipabkp". For a master installation, this
code is not called and the ipabkp file does not exist => delete raises
an error.
When delete fails because the file does not exist, no need to log an
error message.

AES-128-CBC was recently enabled as default wrapping algorithm for transport of secrets.
This change was done in favor of FIPS as crypto-policies disabled 3DES in RHEL9, but
setting AES as default ended-up breaking backwards compatibility with older RHEL systems.
This commit is tuning some defaults so that interoperability with older RHEL systems
works again. The new logic reflects:
- when an old client is calling a new server, it doesn't send any value for wrapping_algo
and the old value is used (3DES), so that the client can decrypt using 3DES.
- when a new client is calling a new server, it sends wrapping_algo = AES128_CBC
- when a new client is calling an old server, it doesn't send any value and the default is
to use 3DES.
Finally, as this logic is able to handle overlapping wrapping algorithm between server and
client, the Option "--wrapping-algo" is hidden from "ipa vault-archive --help" and "ipa
vault-retrieve --help" commands.

The ``ipa-client-install`` command now supports PKINIT for client
enrollment. Existing X.509 client certificates can be used to
authenticate a host.
Also restart KRB5 KDC during ``ipa-certupdate`` so KDC picks up new CA
certificates for PKINIT.
*Requirements*
- The KDC must trust the CA chain of the client certificate.
- The client must be able to verify the KDC's PKINIT cert.
- The host entry must exist. This limitation may be removed in the
future.
- A certmap rule must match the host certificate and map it to a single
host entry.
*Example*
```
ipa-client-install \
--pkinit-identity=FILE:/path/to/cert.pem,/path/to/key.pem \
--pkinit-anchor=/path/to/kdc-ca-bundle.pem

There are several use cases where an explicit IPA CA should be specified

RN: FreeIPA client installer does not add explicit TLS CA configuration

A temporary krb5.conf is created early during client enrollment

If there are multiple servers it is possible that the client

is faster than replication then the client may not exist
on all servers and therefore enrollment will fail.
This was seen in performance testing of how many simultaneous

The API schema is not checked for changes until after a TTL
is expired. A one-hour TTL was hardcoded which makes development
tedious because the only way to force a schema update is to
remember to remove files between invocations.
This adds a new environment variable, schema_ttl, to configure
the TTL returned by the server to schema() calls. This can be
set low to ensure a frequent refresh during development.
If the client is in compat mode, that is if client is working
against a server that doesn't support the schema() command,
then use the client's schema_ttl instead so that the user still
has control.
Re-check validity before writing the cache. This saves us both
a disk write and the possibility of updating the expiration
with a ttl of 0. This can happen if the fingerprint is still
valid (not expired, no language change) the schema check is
skipped so we have no server-provided ttl.

look a bit different:
Added option "('one', 'two')" to Sudo Rule "test"
or
Added option "(u'one', u'Two')" to Sudo Rule "test"
instead of with this change:
Added option "one,two" to Sudo Rule "test"
