smb_auth.sh not working

badspec
Hello!

Im using squid2.6STABLE9 on RHEL4 and trying to setup authentication
on a domain controller using smb_auth.sh. When i browse web, i get a
popup to enter login and password but it doesnt authenticate.
I modified the script smb_auth.sh and i can check that it works
correctly  ie when i enter correct login+password it returns 0 else it
returns 1.

#./smb_auth.sh
Test1 badpasswd
# echo $?
1

#./smb_auth.sh
Test1 goodpasswd
# echo $?
0


Can you help me debugging  ?

Thanks in advance.

Christian.
