pull in just about all of the differences from the crypto-us telnet suite (which includes Kerberos 4 and connection encryption support). Also bring in the Kerberos 5 support from the Heimdal telnet, and frob a little so that it can work with the non-Heimdal telnet suite. There is still some work left to do, specifically: - Add Heimdal's ticket forwarding support to the Berkeley Kerberos 4 module. - Add connection encryption support to the Heimdal Kerberos 5 module. Hints on this can be taken from the MIT Kerberos 5 module which still exists in crypto-us. However, even with the shortcomings listed above, this is a better situation than using the stock Heimdal telnet suite, which does not understand the IPSec policy stuff, and is also based on much older code which contains bugs that we have already fixed in the NetBSD sources.
