Unable to login after AD / LDAP changes

Unable to login after AD / LDAP changes

We have an On Premise installation of ServiceDesk Plus (v9.4.16) with LDAP integration. Recently, our DC that we connect to LDAP had issues and had to be rejoined to the domain. I am now unable to log into ServiceDesk with Domain accounts. Both of our Technician accounts are Domain accounts as well and we do not have a local account with admin access. I know the server is running because I am still receiving emails for new tickets. I'm just not able to login.

                  New to ADSelfService Plus?
