Don't see Windows NT option in authentication tab on the CMC login page

Question

I installed BusinessObjects Enterprise XI 3.1 and installation was successful. We are using Widows NT athentication.  I mapped the Window NT Users. Window NT Users group was populated under u2018users and groupu2019. Everything looks fine.The problem is that I am not able to see Windows NT option in authentication tab on the CMC login page. (I can see only Enterprise, LDAP and Windows AD). I can  see Windows NT option in authentication tab on the infoview login page without problem.
I tried to reconfig the web.xml file ( I replaced 'secEnterprise' with 'secWindowsNT' but it still doesnu2019t work).
web.xml in E:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\warfiles\WebApps\CmcApp\WEB-INF is as followed now
<!-- You can specify the default Authentication types here -->
    <!-- secEnterprise, secLDAP, secWinAD, secSAPR3 -->
    <context-param>
        <param-name>authentication.default</param-name>
        <param-value>secWindowsNT</param-value>  
    </context-param>
    <!-- Choose whether to let the user change the authentication type -->
    <!-- If it isn't shown the default authentication type from above will be used -->
    <context-param>
        <param-name>authentication.visible</param-name>
        <param-value>true</param-value>
Any idea? Thanks

Sherri, on page 457 of the admin guide it says:
"The CMC and other Java-based applications do not support NT
authentication."
I think it's because only windows based app supports windows NT authentication but not java based ones.
I thinkt he CMC is a java based application.
