>Description:
Telnetd(8) dumps core without kerberosV configuration.
>How-To-Repeat:
Try to connect using telnet(1) to no kereberos related configuration
at all.
% telnet land
Trying 210.235.106.85...
Connected to land.
Escape character is '^]'.
Connection closed by foreign host.
>Fix:
At kerberos5_init() in lib/libtelnet/kerberso5.c, it seems that
krb5_init_context()'s return value is ignored.
