MIT Kerberos implements FAST negotiation as specified in RFC 6806
section 11. The implementation relies on the caller to provide a hint
whether FAST armoring must be used.
FAST armor can only be used when both client and KDC have a shared
secret. When KDC is from a trusted domain, there is no way to have a
shared secret between a generic Kerberos client and that KDC.
[MS-KILE] section 3.2.5.4 'Using FAST When the Realm Supports FAST'
allows KILE clients (Kerberos clients) to have local settings that
direct it to enforce use of FAST. This is equal to the current
implementation of 'kinit' utility in MIT Kerberos requiring to use FAST
if armor cache (option '-T') is provided.
[MS-KILE] section 3.3.5.7.4 defines a way for a computer from a
different realm to use compound identity TGS-REQ to create FAST TGS-REQ
explicitly armored with the computer's TGT. However, this method is not
available to IPA framework as we don't have access to the IPA server's
host key. In addition, 'kinit' utility does not support this method.
Active Directory has a policy to force use of FAST when client
advertizes its use. Since we cannot know in advance whether a principal
to obtain initial credentials for belongs to our realm or to a trusted
one due to enterprise principal canonicalization, we have to try to
kinit. Right now we fail unconditionally if FAST couldn't be used and
libkrb5 communication with a KDC from the user realm (e.g. from a
trusted forest) causes enforcement of a FAST.
In the latter case, as we cannot use FAST anyway, try to kinit again
without advertizing FAST. This works even in the situations when FAST
enforcement is enabled on Active Directory side: if client doesn't
advertize FAST capability, it is not required. Additionally, FAST cannot
be used for any practical need for a trusted domain's users yet.

When applying update files to 389 the listeners are disabled.
There is a large try/except around this so that if a failure
happens then the configuration should be automatically
restored.
We've seen multiple cases where this doesn't occur. Best guess
is that users are killing or ^C breaking out of the script.
What happens in that case is that when the next upgrade is run
the configuration is backed up again overwriting the original
values. This leaves dirsrv with no listener on 389.
Add a new state, upgrade-in-progress, so that the backup of the
config information can be skipped when the upgrader is executed
again after a failure.
The idea behind using a new state value is that if additional
attributes are ever backed up we don't need to remember to update
the list of possible saved values to check to decide if the
upgrade is in progress.

[MS-ADTS] 6.1.6.9.3.2 requires msDS-TrustForestTrustInfo attribute of
trusted domain information in Active Directory to conform certain rules.
One side-effect of those rules is that list of UPN suffixes reported
through the netr_DsRGetForestTrustInformation function is dynamically
filtered to deduplicate subordinate suffixes.
It means that if list of UPN suffixes contains the following top level
names (TLNs):
fabrikam.com
sub.fabrikam.com
then netr_DsRGetForestTrustInformation would only return 'fabrikam.com'
as the TLN, fully filtering 'sub.fabrikam.com'.
IPA KDB driver used exact comparison of the UPN suffixes so any
subordinate had to be specified exactly.
Modify logic so that if exact check does not succeed, we validate a
realm to test being a subordinate of the known UPN suffixes. The
subordinate check is done by making sure UPN suffix is at the end of the
test realm and is immediately preceded with a dot.
Because the function to check suffixes potentially called for every
Kerberos principal, precalculate and cache length for each UPN suffix at
the time we retrieve the list of them.

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.
