[squid-users] zimbra and squid_ldap_auth . . .

Hello

I trying to use squid_ldap_auth with zimbra accounts but I?m having a
lot of troubles. Before, I use a line like this from shell to confirm
an OK auth against and LDAP server:

/usr/lib/squid3/squid_ldap_auth -v 3 -b dc=cpe,dc=com -D
cn=Manager,dc=cpe,dc=com -w bindpass -f uid=%s -h 192.168.1.3

But with zimbra not work for me, I?m not trying now to put in
squid.conf, I only need to confirm that the auth param works . . .
the major problem is that I don?t have a way to see the LDAP tree
because zimbra not install a tool like phpldapadmin to see e.g. the
DN to bind as to perform searches or the base dn under which to
search (I assume that is my domain dc=cpe,dc=com) . . . really I need
all possible help . . .

Here some data:
