NT Domain authentication via JAAS & Tomcat

I implemented the NTLoginModule via JAAS at tomcat, the information I require for authentication is username biding with domain,and password. For instance, on the logon.jsp page, the user will input
User name: "myDomain\myUsername"
Password: "myPassword"

In my cases, I meet 3 scenarios as following:

1)Logon with correct domain,username,password, PASSED
2)Logon with wrong domain, correct username, password, FAILED,
but if I logon again with correct domain,username,password, FAILED
3)Other combination, FAILED,but if logon again with the correct
credentials, PASSED.

I check all log files,and can't figure out why #2 is happen, that is,
once I logoned with a wrong domain and correct username/password,
it will fail on the subsequent logon trials.

Anybody meet the similar scenario before? Any hints are
highly appreciated.
