You're not iterating over stdin. Try something like:
martin@apollo:~$ cat test.sh
#!/bin/bash
#iterate over stdin and pull out the relevant fields.
while read LINE
do
if [[ $LINE =~ User-Name ]]; then
USERNAME=$( echo $LINE | awk -F'= ' '{print $2}')
fi
if [[ $LINE =~ User-Password ]]; then
PASSWORD=$( echo $LINE | awk -F'= ' '{print $2}')
fi
done
echo username is $USERNAME
echo password is $PASSWORD
martin@apollo:~$ echo -e "User-Name = \"Fred\"\nUser-Password =
\"supersecret\"" | ./test.sh
username is "Fred"
password is "supersecret"
