Alexander Bokovoy 5213c1e42c ipa-kdb: validate domain SID in incoming PAC for trusted domains for S4U
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.

This is the ipa krb5kdc database backend.

As the KDB interfaces heavily with krb5, we inherit its code style as well.
However, note the following changes:

- no modelines (and different file preamble)
- return types don't require their own line
- single-statement blocks may optionally be braced
- /* and */ do not ever get their own line
- C99 for-loops are permitted (and encouraged)
- a restricted set of other C99 features are permitted

In particular, variable-length arrays, flexible array members, compound
literals, universal character names, and //-style comments are not permitted.

Use of regular malloc/free is preferred over talloc for new code.

By and large, existing code mostly conforms to these requirements.  New code
must conform to them.
