Can a domain partition have a different value for enforce-valid-basic-auth-credentials than the main

Of all our Weblogic applications we have one and only one that requires enforce-valid-basic-auth-credentials to be set to true.  In an SR I opened I was told this was doable with Weblogic MT (Multitenant).  I didn't know MT existed but once I was told that it made sense.  So I've created a domain partition and a new security realm.  But I can't see how to have a different value for enforce-valid-basic-auth-credentials since that is in the <security-configuration> section of the config.xml file and the new partition doesn't appear to get it's own <security-configuration> section.  Searching doesn't seem to find much
