Hi Matthias (and anyone else reading this)
I have tried the solution and cannot get it
working. I replaced this line:
auth_param basic program
/usr/lib/squid/ldap_auth ......
with reference to my script:
"auth_param basic program
/etc/squid/multi_domains.sh"
The /etc/squid/multi_domains.sh was chmod 777'ed
and contains:
#!/bin/sh
# Reading stdin from Squid
INP=`cat`
# Pass stdin to /usr/lib/squid/ldap_auth
DOMAIN1=`echo $INP |
/usr/lib/squid/ldap_auth -R
-b "dc=......"
-D
"cn=Administrator,cn=Users,dc=..........."
-w "........." -f sAMAccountName=%s -h
192.168.1.1`
# Just spit out the result for now
echo $DOMAIN1
Note that this was just a test to make sure the
first part worked before querying two domains and
evaluating. The result was that I received the
authentication prompt in my browser. If I got the
password wrong it would ask upto 2 more times then
access denied, but if I got it correct the browser
would just hang then time-out.
Something weird is going on, because if I add the
following command to the beginning, it gets
ignored when ldap_auth calls it:
echo "hello" >/etc/squid/tmp.txt
Or is that just a permissions issue? If I run the
script from console, it writes the tmp.txt file.
The fact that authentication fails on bad password
and hangs on ok password tells me that the LDAP
part is working. However, the passing of the
stdout back to Squid does not seem to be working.
The weird thing is that Squid knows when I get the
password wrong 3 times.
Regards,
Dietrich (aka grolschie)
