svn rev #21744: trunk/src/lib/kadm5/clnt/

[rra@MIT.EDU]

http://src.mit.edu/fisheye/changelog/krb5/?cs=21744
Commit By: rra
Log Message:
Ticket: 6337

Force tickets acquired by the kadm5 client library via password
authentication to be non-forwardable and non-proxiable, overridding
any [libdefaults] configuration.  This may be necessary at sites that
set forwardable to true by default in their krb5.conf files but
disable forwardable tickets for privileged principals.  Since the
ticket cache acquired by the kadm5 client library is used only for
kadmin operations, where forwardable is not useful or necessary, there
is no reason to ever attempt to obtain forwardable or proxiable tickets
here.
