Currently we only ignore KRB5_PROG_ETYPE_NOSUPP for
Primary:Kerberos-Newer-Keys, but not for Primary:Kerberos.
If a service account has msDS-SupportedEncryptionTypes: 31
and DES keys stored in Primary:Kerberos, we'll pass the
DES key to smb_krb5_keyblock_init_contents(), but may get
KRB5_PROG_ETYPE_NOSUPP.

When reading entries from gencache, wb_cache_rids_to_names() can
return STATUS_SOME_UNMAPPED, which _wbint_LookupRids() does not handle
correctly.
This test enforces this situation by filling gencache with one wbinfo
-R and then erasing the winbindd_cache.tdb. This forces winbind to
enter the domain helper process, which will then read from gencache
filled with the previous wbinfo -R.
Without having the entries cached this does not happen because
wb_cache_rids_to_names() via the do_query: path calls deep inside
calls dcerpc_lsa_lookup_sids_noalloc(), which hides the
STATUS_SOME_UNMAPPED that came in as lsa_LookupSids result value.

smbcacls does not handle DFS paths correctly. This is beacuse once the

not attempt a GET REFERRAL.
We use cli_resolve_path API to perform a DFS path resolution to solve
the above problem.

NBT has a funny thing where it sometimes needs to send a trailing dot as
part of the last component, because the string representation is a user
name. In DNS, "example.com", and "example.com." are the same, both
having three components ("example", "com", ""); in NBT, we want to treat
them differently, with the second form having the three components
("example", "com.", "").
This retains the logic of e6e2ec0001.
Also DNS compression cannot be turned off for NBT.

data : union dnsPropertyData(case 0)
name : 0x00000000 (0)
dump OK
However, the wDataLength is 0. There is not anything in
[MS-DNSP] 2.3.2.1 dnsProperty to describe any special behaviour
for when the id suggests that there is a value, but wDataLength is 0.

We now fail to parse it, because we expect an entry with id DSPROPERTY_ZONE_NS_SERVERS_DA
to therefore have a valid DNS_ADDR_ARRAY (section 2.2.3.2.3).
As context we changed it in our commit fee5c6a424
because of bug https://bugzilla.samba.org/show_bug.cgi?id=14206
which was due to the artificial environment of the fuzzer.
Microsoft advises that Windows also fails to parse this, but
instead of failing the operation, the value is ignored.

The only two callers that pass a root_dir_fid != 0 are reply_ntcreate_and_X()
and call_nt_transact_create(). By moving root_dir_fid processing outside of
SMB_VFS_CREATE_FILE() we can avoid rewriting get_relative_fid_filename() to work
with *AT semantics and dirfsps.
Bonus points: the previous code in both functions passed fname to
filename_convert() which can't really have worked as it is relative to
root_dir_fid so filename_convert() will not be able to stat() the relative path
and it's components.
The only test I can find that uses a root dir_fid is raw.samba3rootdirfid and
that uses a handle on the share root which will work.
