Tool-specific options have precedence over general options. For example, the following properties file uses ldapsearch.port=2389 for ldapsearch requests by the client. All other tools that use the properties file use port=1389.

Example using port=1389:
hostname=server1.example.com
port=1389
ldapsearch.port=2389
bindDN=cn=Directory\ Manager
Example using the dsconfig configuration tool:
hostname=server1.example.com
port=1389
bindDN=cn=Directory\ Manager
dsconfig.bindPasswordFile=/ds/config/password
