You encounter an error while trying to integrate Data Center Security (DCS) Unified Management Console (UMC) with Active Directory using LDAP(port 389).

Unable to connect to the active directory LDAP server using the provided URL.


Domain Controller's "LDAP server signing requirements" policy setting is set to require signing, but Active Directory has not been set for accepting SSL connections.


  •    Change the policy "Domain controller: LDAP server signing requirements" on the Domain Controllers to "None", which will set the LDAP Data signing to not require

               in order to bind with the server. However, if the client requests data signing, the server supports it.

  •    Setting this policy to "none" will also change the following registry setting on all Domain Controllers:
  •    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters\LDAPServerIntegrity=1

              (Note: This is the default setting)
