Re: [squid-users] Help squid_ldap_group W32

Hi Henrik

On Tue 10Aug04 you wrote:

"If you do not need to specify different authorization for different groups and your directory allows direct filtering on group membership then there is no need for squid_ldap_group, only squid_ldap_auth"

Now, I wont try to authenticate and authorizate a user member of internetOK. The base DN is CN=internetOK,OU=utenti,DC=advnet,DC=it and the users are store into OU=utenti,DC=advnet,DC=it

When I have in my squid.conf:
auth_param basic program /Squid/libexec/squid_ldap_auth.exe -b "ou=utenti,dc=advnet,dc=it" -u "CN" -d -v 3 -h "192.168.150.1:389" -D "CN=superadmin,CN=users,DC=advnet,DC=it" -w "pass"
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
auth_param basic casesensitive off

acl autenticati proxy_auth REQUIRED
http_access allow autenticati

The users authenticated can access to internet.

But, if I try to control the membership, none have access to internet:
auth_param basic program /Squid/libexec/squid_ldap_auth.exe -b "ou=utenti,dc=advnet,dc=it" -u "CN" -f "(&(CN=internetOK)(objectClass=group)(member=cn=%u))" -d -v 3 -h "192.168.150.1:389" -D "CN=superadmin,CN=users,DC=advnet,DC=it" -w "pass"

I think the string is wrong, and I try with this -f search options:

-f (&(CN=%u)(objectClass=person)(memberOf=CN=internetOK,OU=utenti,DC=advnet,DC=it))
-f (&(CN=%g)(objectClass=internetOk)(member=CN=%u))

You said me to write this:

-f (&(CN=%g)(objectClass=groupOfPeople)(member=%u))
and I've a question:
              1)Where do I write the name of the group "internetOK"?
                        -f (&(CN=%g)(objectClass=internetOK)(member=%u)) or
                        -f (&(CN=internetOK)(objectClass=group)(member=%u))
                

I try to test a external helper squid_ldap_group from dos command line, but it doesn't work...

Thank you for your help,

Best Regards
Samantha
