svn rev #23516: branches/anonymous/src/kdc/

[hartmans@MIT.EDU]

http://src.mit.edu/fisheye/changelog/krb5/?cs=23516
Commit By: hartmans
Log Message:
Always supply a padata item to the return callback in a preauth plugin so that callback can determine what type of padata it is requested to return.  If there is no item in the request, synthesize an empty one.
