Hey,
First, blur your LogServerOrigin - if it matters or not.
Now, do you get the error on the "Failed Log In" or on any identity records ?!?!?!?!
We had that in the past, and all we did was to drop the SSL HASH from the LDAP objects.
That happened because AD Team changed certificates on their servers... so it will fail since the fingerprint/hash doesn't match anymore .
(see the sk156853 and you will get it, JUST!!!!! leave the Fingerprint empty !!!!! )
This is how an "Failed Log In" looks for us - as you can see the machine was identified properly in AD and mapped to AD groups.
