Description Christopher Schultz 2012-11-13 01:55:35 UTC
The use case is to have one Realm that is configured for lock-out with another that is not: the two should be combined together.

The obvious configuration attempt is this:


Unfortunately, this configuration yields an error:

  No rules found matching 'Server/Service/Engine/Realm/Realm/Realm'

org.apache.catalina.startup.RealmRuleSet.addRuleInstances only goes 2 levels deep when it comes to Realms (that is, only allows "Realm" and "Realm/Realm"). Adding a 3rd level would certainly work here and might be sufficient. Another option would be to configure the digester to allow arbitrary levels of Realm-nesting for even the most pathological cases.

Default increased from 2 levels to 3 and the maximum is supported via a system property.
