When an acl is set on an unmapped repository (this typically happens with dms if the dms module is not installed) a WARN is traced in the log by ContentRepository.getRepositoryMapping():

WARN info.magnolia.cms.beans.config.ContentRepository ContentRepository.java(getRepositoryMapping:564) 17.02.2007 22:43:39 no mapping for the repository [dms]

this should not happen since the code in JCRAuthorizationModule does:

if (!ContentRepository.hasRepositoryMapping(repositoryName))

{ // may be: default users may have permissions for the workflow or dms repositories, but // if the optional modules are not installed no ACL should be set continue; }

workspaceName = ContentRepository.getDefaultWorkspace(name);

but ContentRepository.getDefaultWorkspace(name) does a different check than hasRepositoryMapping() in order to determine if a repository has been registered.
