Hi,

well, the name shouldn't matter...
Now i spent my day with playing with ldapsearch:

ldapsearch -h dhc-server -p 389 -D keppner@dhc-gmbh.com -w sEcReT -x -b
dc=dhc-gmbh,dc=com "(sAMAccountName=keppner)"

returns me all information about my own account; this is, what in
(squid_)ldap_auth is used: "auth_param basic program
/usr/lib/squid/ldap_auth -b dc=dhc-gmbh,dc=com -R -D keppner@dhc-gmbh.com -w
SeCrEt -f sAMAccountName=%s 192.168.42.10" works fine.

This is my squid_ldap_group - command in squid.conf

external_acl_type ldap_group %LOGIN /usr/lib/squid/squid_ldap_group -b
dc=dhc-gmbh,dc=com -D keppner@dhc-gmbh.com -w SeCrEt -f
"(&(cn=Mitarbeiter)(member=uid=%u)) -F (sAMAccountName=%s) -h 192.168.42.10
-p 389

I think, the -F argument is correct, because it works in the auth-command.
Am i right: squid_ldap_group first searches with the -F argument, and checks
this account data against the filter in the -f argument? I don't understand
the meaning of the (member=uid=%u) condition. When i search with ldapsearch
and the Filter CN=Mitarbeiter, then i get a list with all members of the
group Mitarbeiter, where i can see, that i'm a member.

But i still get no access to the cache. In my squid.conf i've written the
external_acl_type and:

acl Mitarbeiter external ldap_group Mitarbeiter

and

http_access allow password dhc Mitarbeiter

the http_access line is inserted below the # INSERT YOUR OWN RULE(S) HERE TO
ALLOW ACCESS FROM YOUR CLIENTS line, dhc stands for our IP-Subnet and
password for the acl password proxy_auth REQUIRED.

Is there an error in the -f definition?

Greetings
Christoph

Maybe a oddity of the Debian packaging, I do not know.
