Give this principal access to the containerdn node when you create it. Ensure that this userid and its password appear in the system properties java.naming.security.principal and java.naming.security.credentials in your JVM properties files.
To use security at the CICS region level, use the CICS runtime principal (cn=CICSSystems,c=US) created by the dfhsns.ldif file, see Step 3. “Build the system name space root node”. This involves some additional steps. Ensure that this userid and its password appear in the system properties java.naming.security.principal and java.naming.security.credentials in your JVM properties files. Additionally, as CICS does not have write access to legacyRoot, CICS will be unable to create its own node (called CICS server 1 in Figure 1), so you must do it manually, and then give the CICS runtime principal (cn=CICSSystems,c=US) write access to this node. This is described below.
