JAAS Form Authentication always failing in Jboss

Question

I have developed web app based on Jboss tutorial examples. In result login page sending me to login-error page. I use DatabaseServerLoginModule. If replace to UsersRolesLoginModule then login is fine.

Google suggest me post http://community.jboss.org/message/141999#141999 but have not answer there.

Jboss log:
