Active Directory can store S/MIME certficates for users and Active Directory servers can be added as X.509 Keyservers in Encryption Management Server under Keys / Keyservers.
However, Active Directory servers require authentication and it is not possible to add authentication credentials using the Encryption Management Server administration console. Without valid Active Directory credentials, Encryption Management Server will be unable to look up user certificates in Active Directory.
The Active Directory server needs to be added as a Keyserver with the following attributes:
X.509 Directory LDAPor
X.509 Directory LDAPS. This will depend whether a secure connection is required. If you choose LDAPS, you will need to import the public certificates from the certificate chain of the Active Directory server certificate. Do this from Keys / Trusted Keys in the administration console.
Once you have added the Keyserver entry for an Active Directory server, you need to update the
keyserver database table with the Distinguished Name and password of an Active Directory user that has permissions to read the S/MIME certificates of other Active Directory users.

Once the Distinguished Name and password for the Active Directory has been added to the
keyserver table, you can add the Keyserver to a mail rule under Mail / Mail Policy in the administration console.
