That sounds like either the machine running telnetd is configured to require des-cbc-crc, or its keytab contains only a des-cbc-crc key. You can fix the latter problem by using ktutil to copy the keytab to a v4 srvtab and back. -- Jeff ________________________________________________ Kerberos mailing list [email protected] https://mailman.mit.edu/mailman/listinfo/kerberos
