I am really hope that you will be able to help me in my problem. I have JBoss 4.2.2, PostgreSQL and application with basic security, here fragment from login-config.xml
and from ...-ds.xml
and each time when I am trying to deploy it I have "SecurityException... PersistenceManager... invalid authentication attempt principal=null", exactly as it was described above. What is more interesting I didn't have this problem before with same settings, but after some changes in application, but not in configurations files, I received this error message... I already tried to compare old and new versions file by file, but I was unable to find anything that can cause something like that. About other security settings I followed by this example
and as I mentioned everything was perfect. I am really hope that you have some ideas...
Thank you in advance!
