Hi, I compiled heimdal for Solaris 2.5.1. I'm using Win 2000 RC2 Server as a KDC. I obtain tickets with kinit, but I'm unable to use telnet/telnetd for kerberos authentication or encryption. Kgetcred complains about a "checksum type unsupported by KDC". Is this a known issue? Thanks Marco Gandolfi CEFRIEL - Milano - Italy
