How To Check Ldap Connection In Windows
Every Windows device on a domain. Every network device that uses ldap queries for AAA, like vpn, firewall, perchance even switches.
jira, nextcloud, vm host machines, that xx year old slice of software on a server nobody has any documentation about.

There are a few ways y'all could practise information technology.
Cake 389 and see what breaks.
You could endeavour combing the event logs.
Or wireshark the DCs and simply filter past 389 after you lot switch everything to 636

In that location are a few ways you could exercise it.
Block 389 and run into what breaks.
You could endeavor combing the event logs.
Or wireshark the DCs and but filter by 389 afterwards you switch everything to 636
pretty much sums information technology up if you lot have not been doing detailed documentation.
I'd start by reviewing your logs to get a good idea and make any needed changes, then make the switch an wait to see if your phone rings

If anything is using explicit ldap binds, it should have a dedicated service account. This style looking at accounts would easily testify what might need to be changed.
Or at least one should use a defended account for ldap binds, and combing trough auth logs would prove where it is used.

What event ID tin can we query? If we collect a list of source IPs, we can practise reverse lookups to run into what's using the LDAP service.
Can LDAP and LDAPS run side by side until everything is converted over to LDAPS?

Yes there sure is. 2886, 2887, 2889. You lot need to add a reg key.
Check out this excellent post.

Make sure yous check all your DC; import the custom event viewer xml on all of them, particularly once yous enable the LDAP Interface effect logging reg key.
This reg key makes your event log fill up apace and may hibernate some upshot 2886/2887.

Unfortunately the only option for ldap signing is On or Off, cant utilize both at the aforementioned time.

Lamentable to dig upward an sometime thread, simply this is relevant to me since I'k trying to observe out what is using LDAP.
I've ready the logging to ii, but I never get 2889 in order to see what is actually authenticating with LDAP. 2887 tells me that there are 5 simple binds performed in the past 24hrs.
I take filtering set to only testify 2886/vii/8/9 and I just e'er come across 2886/7, never anything else...? Any ideas equally to how else I can find out what's using LDAP? I even ran the PS command to bear witness just in case I flubbed the filter and it didn't come up with anything either.

I know this is an old thread, but we are trying to catechumen to LDAPS port 636 and track down what is making unsecured bindings to LDAP. I have the LDAP Interface Events gear up to diagnostic level 2, but I am not getting any event IDs 2886 or 2887 when I brand unsecured bindings over port 389.
I could probably use Wireshark to trace the LDAP calls over port 389 but I want to make sure there is nothing else wrong with the NTDS logging settings. There are also many many 1535 events showing up that I cannot figure out.
