You will need to use a pty instead of a pipe to run kinit that way: it
requires a terminal, or something that looks like one. The error is
because it is performing a terminal-specific device control operation
(switching off key echo).

You might want to look at something like "expect" which is available as
a library for many different programming languages. However, you'd do
better to find a Kerberos library for that language instead.
