Hi Jaikiran, Example which you suggested implemets DatabaseServerLoginModule. Let me tell my case in details following is my jaas.login.config file myloginmodule{ com.login.test.PasswordLoginModule required authenticator = "com.login.test.authenticators.PasswordAuthImpl digestAlgo = "SHA1" datasource = "" }; now PasswordAuthImpl contains method authenticate(Map, username,pwd) to authenticate user. Now my question is where do i put my jaas.login.config file in jboss so that it works as it is. and for db what changes i need to make?
