/usr/local is an odd place to have the smb_auth binary. Run "which smb_auth" from the command line - is it in /usr/local, or somewhere else? If it's somewhere else, change your squid.conf and try it again. Also, what are the permissions on smb_auth?

Make sure the program is executable by the user Squid runs as. Adam
