Creating SSL Entries in the Directory Service

Create SSL entries in the Replication Server directory service—such as the interfaces file or an LDAP server, which defines the server address and port numbers, and determines security protocols that are enforced for client connections.

1. Verify that all attempts to connect to a master or query entry in a directory service with an SSL filter supports the SSL protocol.
   For example, suppose a primary Replication Server (SYBSRV1) and a replicate Replication Server (SYBSRV2) use the Transmission Control Protocol (TCP) and the SSL protocol for communication.
   Entries in the interfaces file might look like this:

   SYBSRV1
   query tcp myserver sybasehost1 5001 ssl
   master tcp myserver sybasehost1 5001 ssl

   SYBSRV2
   query tcp myserver sybasehost2 4001 ssl
   master tcp myserver sybasehost2 4001 ssl

2. You can also configure Replication Server to accept SSL connections and, at the same time, have other connections that accept clear text or use security mechanisms such as DCE and Kerberos.
   To support both SSL and other connection protocols, you must use multiple interfaces files.
   For example, a typical interfaces file entry that supports the TCP and both SSL and clear text connections looks like this:

   SYBSRV1
   query tcp myserver sybasehost1 5001 ssl
   master tcp myserver sybasehost1 5001 ssl
   master tcp myserver sybasehost1 5001

3. The interfaces file master line entries allow SYBSRV1 to listen for both SSL and clear text connections. To make sure that SYBSRV1 sends queries to SYBSRV2 using SSL, there must be a single query entry in the interfaces file for SYBSRV1.
   To allow SYBSRV1 to send queries to other servers using a different protocol, use a separate interfaces file.
