[jcifs] NullPointerException when trying to authenticate against domain name > 15 chars

[Øyvind Harboe]

I'm getting an NPE when trying to authenticate against a Windows 2003
domain controller.


More info:

- the domain name I'm using is ca. 30 chars. In the error logs, I see
the domain name being chopped off at 15 chars and converted to
uppercase. (Replaced w/YYYYYY.XXXXXXXXX below). I believe this happens
in the constructor of jcifs.netbios.Name:
       public Name( String name, int hexCode, String scope ) {
        if( name.length() > 15 ) {
            name = name.substring( 0, 15 );
        }
        this.name = name.toUpperCase();


- The same problem? http://lists.samba.org/archive/jcifs/2006-July/006394.html


- I find the two exceptions below in the log.
