Summary

When accessing the DSM console using an Active Directory account, the following error message appears:

Certificate error connecting to LDAP server. Please contact the system administrator.

Certificate Error

Details
Public

The issue occurs because of one of the following:

  • The Active Directory server does not have SSL enabled. To use SSL-based access methods, SSL must be enabled, which is often not the default condition. Port 636 is used for SSL connections.
  • There is a change in the certificate or it is expired. To resolve the issue:
    1. Log in to DSM using the default account "MasterAdmin".
    2. For Deep Security 9.5 and above, go to Administration > User Management > Users.
      For Deep Security 8.0, go to System > Users.
    3. Click Synchronize with Directory.
    4. Select Add/Update Certificate, and then click Next. The DSM will now try to synchronize with Active Directory to update the certificate.
    5. Click Accept and click Next.
    6. Log out of the DSM and then log in using the Active Directory account.
