Some non-GSSAPI implementations that instead try to create compatible packets by wrapping krb5_mk_req()
can trigger a NULL authenticator here. Assume this to be equvilent to specifying an all-zero
channel bindings and some reasonable (fixed) flags.
This was seen in the wild, with a Huawei Unified Storage System S5500 V3 against the AD DC

A backend can return this if asked with HDB_F_GET_CLIENT|HDB_F_FOR_AS_REQ
for a KRB5_NT_ENTERPRISE_PRINCIPAL record or for HDB_F_GET_SERVER | HDB_F_FOR_TGS_REQ.
entry_ex->entry.principal->realm needs to return the real realm of the principal
(or at least a the realm of the next cross-realm trust hop).
This is needed to route enterprise principals between AD domain trusts.

When sending a Kerberos request, if at least one of the available
KDCs repeatedly replies with an error response of
KRB5KDC_ERR_SVC_UNAVAILABLE, and all other KDCs, if there are any,
do not reply at all or cannot be contacted, then the code repeatedly
retries to send the request in an endless loop.
This is fixed in upstream (post 1.5 branch) heimdal but the code
there is vastly refactored, so this is an independent fix to the issue.

FreeIPA can generate tickets with a client principal of
'host/hostname.example.com'.
verify_logonname() should just verify the principal name
in the PAC_LOGON_NAME is the same as the principal of
the client principal (without realm) of the ticket.

tmp.data is uninitialized in the fwrite call
Hopefully I don't create a problem here: If tmp.data is supposed to be randomly
set, I think the right fix would have been to explicitly call a random function
initializing it.
<jra@samba.org>
------------------------------------------------------------
I have looked through the code carefully. Your fix is safe.
The first entry in the replay file created in krb5_rc_initialize()
is only used to store the 'krb5_deltat auth_lifespan' value, the
associated data[16] value is never looked at. (Look at the
code in krb5_rc_store() and krb5_rc_get_lifespan() to confirm).
Only subsequent data[16] values are checked with memcmp.

I think Coverity is right here: Before the preceding call to
krb5_make_principal we already krb5_free_principal(ctx, tmp_creds.server)
without wiping out tmp_creds.server. The call to krb5_make_principal only
stores something fresh when it also returns 0 a.k.a. success.

The error Coverity complains about is in the malloc. krb5_enctypes is
