>Description:
	While the cli doesn't expose it, there's a "setkey" rpc in the
	kadm5 protocol.  Using this provides an elegant way to handle
	adding service keys such as for afs with less downtime.
>How-To-Repeat:
	Write a program which calls kadm5_setkey_principal_3.  Run it on
	a principal.  Then run kadmin & look at the resulting key type.
	In 1.4.3 this worked fine; in stock 1.6.3, this results
	in an enctype and kvno of 0.
>Fix:
	Run-time workaround, don't call kadm5_setkey_principal_3.
	Compile-time fix, apply the patch in
	/afs/umich.edu/group/itd/build/mdw/krb5.15x/patches/krb5-1.6.3-setkey1.patch
