Where to call rmdir does not matter, but that should avoid the TOCTOU

We never use msgid=0, see tldap_next_msgid(). RFC4511 section 4.4.1
says that the unsolicited disconnect response uses msgid 0. We don't
parse this message, which supposedly is an extended response: Windows
up to 2019 sends an extended response in an ASN.1 encoding that does
not match RFC4511.

We need to make sure that winbind's idmap_ad deals fine with an
expired krb ticket used to connect to AD via LDAP. In a customer
situation we have seen the RFC4511 section 4.4.1 unsolicited ldap exop
response coming through, but the TCP disconnect that Windows seems to
do after that did not make it. Winbind deals fine with a TCP
disconnect, but right now it does not handle just the section 4.4.1
response properly: It completely hangs.
This test requests a ticket valid for 5 seconds and makes the LDAP
server postpone the TCP disconnect after the ticket expiry for 10
seconds. The tests that winbind reacts to the ticket expiry exop
response by making sure in this situation the wbinfo call running into
the issue takes less than 8 seconds. If it did not look at the expiry
exop response, it would take more than 10 seconds.

The callback of "req" might have destroyed "ld", we can't reference
this anymore after calling tevent_req_done(req). Defer calling the

See RFC4511 section 4.4.1 and
https://lists.samba.org/archive/cifs-protocol/2020-August/003515.html
for details: Windows terminates LDAP connections when the krb5 ticket
expires, Samba should do the same. This patch slightly deviates from
Windows behaviour by sending a LDAP exop response with msgid 0 that is
ASN1-encoded conforming to RFC4511.

LDAP connections should time out when the kerberos ticket used to authenticate
expires. Windows does this with a RFC4511 section 4.4.1 message (that as of
August 2020 is encoded not according to the RFC) followed by a TCP disconnect.
ldb sees the section 4.4.1 as a protocol violation and returns
LDB_ERR_PROTOCOL_ERROR.
