lsh-krb-checkpw - program to check a Kerberos username/password combination


lsh-krb-checkpw username-to-check


This manual page documents briefly the lsh-krb-checkpw command. This manual page was written for the Debian distribution because the original program does not have a manual page. Instead, it has documentation in the GNU Info format; see below.

lsh-krb-checkpw is a program that checks if a username and password combination is valid for login by doing a kerberos lookup. It is designed to be used as a password helper program for lshd (8), (eg. --password-helper=/usr/sbin/lsh-krb-checkpw.

lsh-krb-checkpw takes one required argument, which is the username, and reads the password from stdin, then returns 0 if the password is valid, or 1 otherwise. Note that the password must be supplied exactly, ie. there must be no newline after the password, so if invoking from a shell, just type "<your-password><CTRL-D>".


lsh(1), lshd(8). The programs are documented fully by Lsh, available via the Info system.
