If you are using LDAPS authentication, you must export an LDAPS certificate from your Windows Server to upload the Barracuda Web Security Gateway. You configure the LDAP Port with the port number on which the server listens for LDAP (636 for LDAPS) connections, on the USERS/GROUPS > Authentication page of the Barracuda Web Security Gateway web interface.
After you export the certificate from your Windows Server, follow instructions for uploading the certificate to your Barracuda Web Security Gateway in How to Enable LDAP Domain User Authentication.
