[jcifs] Authentication module

[Kotapally, Srini]

Hi all,

I am trying to implement jcifs to authentication for one of my webapps.
I have setup a test environment on my PC where I am troubleshooting this
issue.  What I have done is as follow.  I have a webapp (the example app
from the tomcat dev, and I have configured it as described in the jcifs
documentation.  I keep getting a arrayindexoutofboundsexception.
Essentially I want tomcat to authenticate against our Active Directory
and then pass the user ID in the header to the webapp (I may need to do
this through some java code, but I want the basic setup to work first).
Can you please advise where I am going wrong?

I am using tomcat 5.5.9 and jcifs 1.3.1 (latest) running on java
j2sdk1.4.2_13.  Here is my web.xml:

    <filter>
        <filter-name>NtlmHttpFilter</filter-name>

            <param-name>jcifs.smb.client.password</param-name>
            <param-value>password</param-value>
        </init-param>
        </filter>
    <filter-mapping>
        <filter-name>NtlmHttpFilter</filter-name>
        <servlet-name>CheckNtlm</servlet-name>

        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
        <dispatcher>ERROR</dispatcher>
    </filter-mapping>
