The cache be enabled (default) or disabled using
ldap_cache=True/False.
This cache is per-request so is not expected to grow
particularly large except in the case of a large batch

The key to the cache entry is the dn of the object
being requested.
Any write to or referencing a cached dn is evicted from
the cache.
The set of attributes is somewhat taken into consideration.
"*" does not always match everything being asked for by
a plugin so unless the requested set of attributes is a
direct subset of what is cached it will be re-fetched. Err
on the side of safety.
Despite this rather conserative approach to caching 29%
of queries are saved with ipatests/xmlrpc_tests/*

FreeIPA's Python and C code used different approaches to get the FQDN of
the host. Some places assumed that gethostname() returns a FQDN. Other
code paths used glibc's resolver to resolve the current node name to a
FQDN.
Python code now uses the ipalib.constants.FQDN where a fully qualified
domain name is expected. The variable is initialized only once and avoids
potential DNS lookups.
C code uses a new helper function ipa_gethostfqdn() in util package. The
function implements similar logic as gethostfqdn() except it uses more
modern getaddrinfo(). The result is cached as well.

Commit 49cf5ec64b fixed a bug that
prevented migration from externally-signed to self-signed IPA CA.
But it introduced a subtle new issue: certmonger-initiated renewal
renews an externally-signed IPA CA as a self-signed CA.
To resolve this issue, introduce the `--force-self-signed' flag for
the dogtag-ipa-ca-renew-agent script. Add another certmonger CA
definition that calls this script with the `--force-self-signed'
flag. Update dogtag-ipa-ca-renew-agent to only issue a self-signed
CA certificate if the existing certificate is self-signed or if
`--force-self-signed' was given. Update `ipa-cacert-manage renew'
to supply `--force-self-signed' when appropriate.
As a result of these changes, certmonger-initiated renewal of an
externally-signed IPA CA certificate will not issue a self-signed
certificate.

Client connections no longer override TLS version range and ciphers by
default. Instead clients use the default settings from the system's
crypto policy.
Minimum TLS version is now TLS 1.2. The default crypto policy on
RHEL 8 sets TLS 1.2 as minimum version, while Fedora 31 sets TLS 1.0 as
minimum version. The minimum version is configured with OpenSSL 1.1.1
APIs. Python 3.6 lacks the setters to override the system policy.
The effective minimum version is always TLS 1.2, because FreeIPA

Currently, RA agent certificate is issued using caServerCert profile.
This has unfortunate side effect of asserting id-pk-serverAuth EKU which
is not really needed for RA agent. If IPA CA certificate adds SAN DNS
constraints into issued certificates, presence of id-pk-serverAuth EKU
forces NSS (and other crypto libraries) to validate CN value with
regards to SAN DNS constraints, due to historical use of CN bearing DNS
name.
Since RA agent certificate has 'CN=IPA RA', it is guaranteed to fail
the check.
Default IPA CA configuration does *not* add SAN DNS constraints into RA
agent certificate. However, it is better to be prepared to such
behavior.
