LDAP Authentication not working on DC
LDAP Authentication not working on new Domain Controller. We had a Domain controller that was migrated from 2003 to 2008 ad in Dec instead of migrating we started fresh with a Brand new 2019 Server Host Server and stood uup a new DC without migrating. We wanted to avoid bringing over bad users and GP's that are no longer needed.
Every since the new Server has been online we can not get the LDAP portion to work to authenticate users from things like our Firewall and SharePoint all these systems say Error using LDAP to Authenticate

Thanks for your help, we found it to be that we did not have the LDAP Binding credential correct we were using the Username instead of the Display Name .
Such as : CN=Display Name,CN=Users,DC=MyDomain, DC=company ,DC=local
Such as : CN=Display Name,CN=Users,DC=MyDomain,

If the DN is required on 2019, it would also have been required on 2008 and 2003
Does the DC have a suitable certificate for 636 ?
Is the Firewall on the DC blocking access ?
Have you tested on the DC with a LDAP Browser ?
