AD/LDAP Authentication Over SSL



This is only applicable to on-premise deployments.

This guide will show you the steps to configure AD or LDAP over SSL. Note that this configuration is portal-wide and affects all tenants (accounts) within the Appspace instance.

We will be covering two key sections:

Before we start, here are a few types of certification that is relevant for this guide:

  • Self-Signed – The certificate is self-signed and needs to be imported into the trust store of the Appspace server.
  • Private CA-Signed (Trusted) – The certificate is signed by a trusted private authority therefore no manual configuration is needed.
  • Private CA-Signed (Untrusted) – The certificate is signed by an untrusted private authority therefore that authority’s certificate needs to be imported into the trust store of the Appspace server.
  • CA-Signed – The certificate is signed by a trusted CA therefore no manual configuration is needed.



This feature has been designed to work with a flat Active Directory structure.

  • An AD or LDAP server with SSL enabled.
  • The SSL certificate CN must match the FQDN of the AD or LDAP server.
  • The SSL certificate must be valid and be certified from a trusted Certificate Authority (CA).
  • Windows Server user credential on the Appspace server with local administrator privileges.
  • Appspace user credential with Portal Administrator role.
  • Basic knowledge of navigating Windows Server 2008 and IIS (Internet Information Services).

Importing a Self-Signed/Private CA-Signed SSL Certificate

Follow these steps to import a self-signed/private CA-signed SSL certificate into Appspace Server’s trust store:
