I think I have already said this, but kerberos is much more secure than
ldaps, the password never leaves the computer. As for SSH, you can use
kerberos for this, no ssh keys or passwords.

There is is nothing wrong with a service user with a never expiring
password, just as long as you are using kerberos and the user never
logs in anywhere.
