* default.exp (start_kerberos_daemons): New methodology for

		starting KDC so that the KDC will not hang on a full
		output buffer which is being ignored.
		(setup_kerberos_files): Enable des3 encryption types.

The first problem was seen on Suns where I previously set the logging
for the kdc to stderr, and then ignored the output after the server was
running.

The second exercised the bug that sam just fixed in mixing in the des3
encryption types.
