Description of problem:
The squid authentication module fails to authenticate users against the NT 
Domain controller. 

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Edit squid.conf appropriately for user authentication and restart squid
2. run the following to attempt authentication:
/usr/local/bin/smb_auth -W DOMAIN -d
USERNAME PASSWORD

OR
Just try to get authenticated by setting up a computer to go through the proxy 
and "surf" to a URL. It will prompt for username and password and fail every 
time user tries to authenticate.
	

Actual Results:  An error message is displayed saying that it can't find 
nmblookup.

Expected Results:  If the USERNAME and PASSWORD are valid it should output the 
end result of "OK"

Additional info:

Problem is that the file /usr/lib/squid/smb_auth.sh grabs the wrong value for 
$SAMBAPREFIX. There are 2 possible solutions...

1. compile the package with appropriate command-line options such that the 
$SAMBAPREFIX variable will be set properly.

2. add the following line near the top of /usr/lib/squid/smb_auth.sh:
export SAMBAPREFIX="/usr"

Solution #2 assumes user is running the version of Squid and Samba that RH7.2 
comes with. Not tested with any other version of Squid and/or Samba.
