[jcifs] NTLM HTTP Authentication: Strange scenario

[Guofeng Zhang]

Our web application use NTLM HTTP Authentication to single-sign in
users.

 

When IE pop up the Windows login dialog box, if an incorrect login
in/password is input, our application will send a form-based login page
to IE. I input the correct login data in the login form, a login error
page is displayed. I then input the same login data again in the login
error page, I login successfully. I find that the data input at first
time in the login form is not sent to the application server. The value
displayed at the application sever is null.

 

I do not know why IE behavior in this way (it does not send the login
data at the first time). 

 

I use JBoss 3.2.5. I implement an authenticator based on the NTLM HTTP
filter, and plug in the authenticator to JBoss.

 

Thanks for your help very much.
