Query on SPNEGO

[prashant sodhiya]

Hi All,

    I have a query on the SPNEGO, a new feature introduced in krb5-1.5 release.This piece of code is donated by SUN, but they have not included the entire Copyright for the SPNEGO code ?  All it says is,
/*
 * Copyright 2004 Sun Microsystems, Inc.  All rights reserved.
 * Use is subject to license terms.
 */

Where are the licence terms ? 
Mech-glue too has been donated by SUN , but they have a well written copyright for that piece of code? Does the copyright for mech-glue apply as is for the SPNEGO code as well ? Anyone clear on this , any inputs will be appreciated.
Also contact email to relevant SUN folks might also prove helpful , incase this stuff was not clarified by MIT.

Thanks much,
Prashant
