Auth-user-pass-verify /usr/local/sbin/verify.sh via-file not working/authenticat

[m4f1050]

I need help with auth-user-pass-verify.  I was able to use this script on my dd-wrt router and it worked perfect, but when I try to use it on pfSense OpenVPN it does not authenticate me.  Can someone please help me fix this?

#!/bin/sh

 ## format: username:password username:password ...
 ## you can even have same usernames with different passwords
 USERS='user1:pass1 user2:pass2 user3:pass3'

 ## you could put username:password in
 ## a separate file and read it like this
 #USERS=`cat file_with_users`

 vpn_verify() {
     if [[ ! $1 ]] || [[ ! $2 ]]; then
         #echo "No username or password: $*"
         exit 1
     fi

     ## it can also be done with grep or sed
     for i in $USERS; do
         if [[ "$i" == "$1:$2" ]]; then

             ## you can add here logging of users
             ## if you have enough space for log file
             #echo `date` $1:$2 >> your_log_file

             exit 0
         fi
     done
 }

 if [[ ! $1 ]] || [[ ! -e $1 ]]; then
     #echo "No file"
     exit 1
 fi

 ## $1 is file name which contains
 ## passed username and password
 vpn_verify `cat $1`

 #echo "No user with this password found"
 exit 1
