Hello,
We have run into a LDAP issue recently that has me stumped. We promoted a brand new domain controller that we spun up on windows server 2019. we then migrated one of our domain controllers onto this server. Once we did that we shut down the original domain controller leaving us with DC2 (the new domain controller on windows server 2019) and DC1(our original domain controller on windows server 2012 r2). For some reason our other servers which use LDAP have been having issues pulling credentials. We have a Papercut server which is unable to pull active directory credentials, as well our Radius server is on another server which is unable to pull credentials. I have been unable to find any clear cut support article on what could be the cause of this issue or any resolution. Any thoughts you might have would be greatly appreciated
