commit 85dd55a5fef0049660126bdcd48abfa1c48da259
Author: Ralph Boehme <s...@samba.org>
Date: Thu Jul 24 12:59:30 2025 +0200
libads: change netlogon_pings() behaviour wrt to min_servers parameter
Currently if a caller passes min_servers=X with X>1, netlogon_pings() will
fail
if it can't contact X DCs. This is not really what we want. What we want
is: we
want at least one DC, and up to X.
Change implemenentation in that sense and rename the min_servers argument to
wanted_servers to express this behaviour change.

idmap_ad: add and use ldap_timeout and fix LDAP server failover
The key parts are:
1. If an LDAP search fails with the hardcoded fatal error, remove the
retry. That would only retry the query against the same server, taken
from the DCINFO cache key. Instead, force a DC rediscovery.
2. Set a default ldap_timeout and pass it to tldap_search(). This
avoids tldap_search() hanging forever on a stale TCP connection.
3. The LDAP server idmap_ad is using is not necessarily the same DC
we're using for RPC, so in case we learn about a dead DC, put it in
the negative-conn-cache.

Needed to detect unresponsive LDAP servers, otherwise we might be sitting
up to
924.6 seconds after sending a request before the kernel notifies us of a
