Hi all,
I'm trying to implement checkpassword authentication with a simple bash
script. In some way I can't get the password from file descriptor 3.
The start of script looks like this:
#!/bin/bash
read -d '\0' -r -u 3
USERNAME="${REPLY}"
read -d '\0' -r -u 3
PASSWORD="${REPLY}"
if [ -z "${USERNAME}" ] || [ -z "${PASSWORD}" ]
then
exit 111
fi
It always exits with 111, because PASSWORD is empty. In whatever way I try
to retrieve data from fd3, I never happen to get more data than the username.
Is this a known problem? Am I doing something silly? Replies are much
appreciated!

FYI: GSSAPI auth works perfect and PAM worked before switching to
checkpassword too.
