I have used the database login module, but never using it the way you are trying to. If I ran into your problems, I would look at security/src/main/org/jboss/security/auth/spi/DatabaseServerLoginModule.java in the source code, probably adding some logging code to figure out what is going wrong. Sorry that this doesn't answer your exact question, but hopefully this will give you somewhere to look to debug the problem.
