But your here document contains the text of an echo command, not a "y".
What are you thinking here?

Sounds like nisclient was coded badly and doesn't recognise end-of-file.

Well, this doesn't "cycles through a word list", presumably from a file
called "credlist.txt". Instead, it cycles through a wordlist whose
entire content is the single word "credlist.txt".
You want to go:
while read user
do
...
done <credlist.txt
instead.
| # Start of Here document
| #
| nisclient -cl newpass $user <<- FINIS
| echo "Changed $user account password"
| FINIS
If you want to enter a 'y' into nisclient, then you probably want to do
this:
if echo y | nisclient -cl newpass $user
then
echo "Changed $user account password"
fi
I don't understand why you want a here document at all n this case.

This output itself should tell you you are invoking nisclient
incorrectly, with $user being "credlist.txt". Did you read it?

This is nisclient being stupid. It legitimately rejects the text:
echo "Changed credlist.txt account password"
as neither "y" nor "n" and asks again, but then doesn't recognise end of
input as such, and asks again forever.
I'd also consult the manual entry for nisclient and see if it has a
command line option to mean 'y', avoiding the question.

C'mon. Take the plunge. By the time you go through rehab the first time,
you'll be surrounded by the most interesting people, and if it takes years
off of your life, don't sweat it. They'll be the last ones anyway.
