Correct. NetBSD has removed most kerberos support from 4.4lite to
comply with export restrictions.
Thorsten Lockert, <tholo@SigmaSoft.COM>, has reintegrated a bunch
as of 6 Mar of last year, in PR 157, as of 0.9-current of that date.
It doesn't seem to include Kerberized telnet....

No, it affects the Cray, and 44lite telnets as well. Additionally,
the next release of Cygnus Network Security (which is the easiest way
to get Kerberos udner NetBSD) will include a kerberized telnet client.
It will, of course, have this fix in it.
