You can try to set traces into the code of your realm class, if it's a
custom realm : to watch the query executed ,  to watch the
user/password passed from browser, to catch exceptions and print stack
trace ...
If you dont have a custom realm, you can try to create one for testing

Can you paste your server.xml conf ? Only realm parts (all), without
sensible data

Good luck
