OLEXP: How to Add Socket Support for Secure Directory Service Servers

MORE INFORMATION

The Secure Socket Layer (SSL) standard uses different sockets for directory services and secure LDAP servers. Directory services default to socket port 389, and secure LDAP servers default to socket port 636.

To change the socket port of a secure LDAP server, follow these steps:

1. If you have not already done so, create an account for the secure LDAP server. To do so, follow these steps in Outlook Express:
   1. On the Tools menu, click Accounts.
   2. On the Directory Service tab, click Add, point to Directory Service, and then proceed through the Internet Connection Wizard to configure the LDAP server.
2. On the Tools menu, click Accounts.
3. On the Directory Service tab, click the secure LDAP server you want to configure, and then click Properties.
4. On the Advanced tab, click the "This server requires a secure connection (SSL)" check box to select it. The number "636" (no quotation marks) appears in the Directory Service (LDAP) box.
5. Click OK, and then click Close.

Sockets is a standard used by Transmission Control Protocol/Internet Protocol (TCP/IP) to provide communications between programs requesting services (clients) and programs providing services (servers). Each socket is used for specific types of services.
