Active Directories Settings

Active Directories page is used to integrate MetaDefender Vault with your organization Active Directory in order to synchronize users.

In order to be able to set up Active Directory integration, the account used by Vault to connect to Active Directory will require read permissions in Active Directory.

Note: the default port for LDAP is 389 and the default port for LDAPS is 636

Authentication Type

None: U se basic authentication (simple bind)

Secure: Request secure authentication
Note: AD DS uses Kerberos and possibly NTLM to authenticate the client

If your assigned license key does not contain enough user licenses the Active Directory synchronization will report the following message:

If this happens, please contact OPSWAT Sales for a license upgrade or, alternatively, you can go back to User Filtering Configuration step and exclude more users.


Please note that It is also possible to become over licensed at a later moment in time if new users are continuously added in your Active Directory. If this happens, a notification will appear and an email notification will be sent to all the administrators. New users would not be able to log in until the over licensed state is resolved by either removing some users from the User Filtering Configuration or by requesting a license upgrade. Existing users (prior to becoming over licensed) will still be able to log in and upload files normally.
