Issue in jcifs v1.3.12

[Venuganan]

Hi,
Am using jcifs-1.3.12 in my application for retreiving the client username in the application. Since i wanted to get the username from IE7 browsers and also vista machine, therefore i should use jcifs with ntlmv2, I followed the steps suggested in the docs and used the following
in my "web.xml":
<init-param>
   <param-name>jcifs.smb.lmCompatibility</param-name>
   <param-value>5</param-value>
</init-param>
<init-param>
   <param-name>jcifs.smb.client.useExtendedSecurity</param-name>
   <param-value>true</param-value>
</init-param>

yet i have the following issue,
jcifs.smb.SmbException
java.lang.NullPointerException
        at jcifs.smb.NtlmPasswordAuthentication.nTOWFv2(NtlmPasswordAuthentication.java:207)
