The LDAP namespace structure

The LDAP namespace structure used by WebSphere® Application Server Version 4 for z/OS® and OS/390®, is a convenient structure for use in a CICS® environment.
Note: WebSphere Application Server Version 5 and later use a COS Naming Server by default and support LDAP only for backwards compatibility with WebSphere Application Server Version 4.

There are two important nodes in the LDAP namespace structure used by WebSphere, the container root, and the legacy root.
