LSH-KRB-CHECKPW(8)

💖 LSH-KRB-CHECKPW 💖

okay so bestie, welcome to the lsh-krb-checkpw page from the lsh manuals — it's manual section 8, aka the big-girl sysadmin section 💅

✨ NAME ✨

lsh-krb-checkpw — a whole program whose entire job is checking whether a Kerberos username + password combo is valid 🎀

🌸 SYNOPSIS 🌸

lsh-krb-checkpw username-to-check

🦋 DESCRIPTION 🦋

So this page is a lil' quick-and-dirty doc for the lsh-krb-checkpw command. And here's the tea: it was written for the Debian distribution specifically because the original program simply does not have a manual page. Not me being dramatic, that's just the facts 😭. Instead, the real documentation lives in GNU Info format — more on that down below in SEE ALSO, bestie 🫶

lsh-krb-checkpw is the program that checks whether a username and password combination is valid for login, and it does this by doing a kerberos lookup ✨. It's designed to be used as a password helper program for lshd (8) — like, for example:

--password-helper=/usr/sbin/lsh-krb-checkpw

lsh-krb-checkpw takes one required argument, which is the username 👑, and then it reads the password from stdin. After that it returns 0 if the password is valid, or 1 otherwise 💀.

⚠️ ok this part is IMPORTANT, do not skip it: the password must be supplied exactly, meaning there must be no newline after the password. So if you're invoking it from a shell, you just type <your-password><CTRL-D> — that's your password, then literally press CTRL-D. no enter. no vibes. exact. periodt 🎀
