XADM: LDAP Port for SSL Is Not Configurable In Exchange

ID: Q179309

The information in this article applies to:

Microsoft Exchange Server, versions 5.5, 5.0

SUMMARY

In Microsoft Exchange Server versions 5.0 and 5.5, the Secure Sockets Layer (SSL) port for Lightweight Directory Access Protocol (LDAP) can not be changed; it is fixed on port 636.

MORE INFORMATION

Currently, all clients are configured to connect to port 636 for SSL LDAP directory queries. This port is not configurable from the client, so there is no reason to change it on the server. Doing so would make clients unable to connect for these queries. Normal LDAP queries are configured for Port 389. For more information on configuring this port, please see the following Microsoft Knowledge Base article:
