Right - same problem (NameNotFoundException) after changing jboss.xml and jboss-web.xml to a security-domain of SPDB instead of "java:/jaas/SPDB"... I'm going to dig into that and see why login-config.xml is (seemingly) not being read. I'm not sure I fully understand the relationship between login-config.xml and client/auth.conf yet. I'm going to see if I can find more documentation on that. I have tried this both with an entry for SPDB in auth.conf and without an entry there, and it doesn't make a difference either way...
