KDB driver extensively uses NDR parsing and marshalling code provided by
Samba libraries. Since these libraries are internal to Samba, they often
change structures without updating SONAME. Typical changes include
adding new structures, so we should require samba-client-libs we were
built against.
There used to be %requires_eq macros in RPM but it was removed from
Fedora some time ago. We need greater than or equal version of it, thus
%ipa_requires_gt is defined in the spec file.

Previously, ipadb_check_logon_info() was called only for cross-realm
case. Now we call it for both in-realm and cross-realm cases. In case of
the S4U2Proxy, we would be passed a PAC of the original caller which
might be a principal from the trusted realm. We cannot validate that PAC
against our local client DB entry because this is the proxy entry which
is guaranteed to have different SID.
In such case, validate the SID of the domain in PAC against our realm
and any trusted doman but skip an additional check of the DB entry in
the S4U2Proxy case.

When working with aliased entries, we need a reliable way to detect
whether two principals reference the same database entry. This is
important in S4U checks.
Ideally, we should be using SIDs for these checks as S4U requires PAC
record presence which cannot be issued without a SID associated with an
entry. This is true for user principals and a number of host/service
principals associated with Samba. Other service principals do not have
SIDs because we do not allocate POSIX IDs to them in FreeIPA. When PAC
is issued for these principals, they get SID of a domain computer or
domain controller depending on their placement (IPA client or IPA
server).
Since 389-ds always returns unique entry DN for the same entry, rely on
this value instead. We could have used ipaUniqueID but for Kerberos
principals created through the KDB (kadmin/kdb5_util) we don't have
ipaUniqueID in the entry.

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.

The purpose of changing of default builddir was noexec mount option for

Azure lacks this issue the PIP_BUILD can be safely removed.
Note: pip 21.3 just ignores this env variable, which is more than can be
said for the command line option. It's better to clean it up, since the
behaviour may be changed in future.
