Description of problem:
Current implementation of kinit does not echo any character when entering password. From my perspective, this has security implications - by not giving user ANY feedback, it is more prone for leaking password.
Simple exemplary situation - wrong window focused, on different monitor.
Provide user with option to enable echoing asterisks, as usual, or cycle through few characters to show activity, without giving password length in easy way. (for example randomly print one of the characters .oO :) )
Version-Release number of selected component (if applicable):
This is how most password tools on unix-likes (e.g., passwd and friends) behave, so there isn't a very large impetus to change this behavior. Certainly the default will not change.
