To use security at the containerdn level, use the CICS administration principal (cn=CICSUser,c=us) created by the dfhsns.ldif file (see Step 3. “Build the system name space root node”). 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.
