using ldap for squid authentication

[Catherine Hollnsteiner <cathy@ntsp.nec.co.jp>]

im using openldap for my squid authentication but it fails...
here is the output of my ldap server in debug mode:
-------------------------------------
daemon: select: listen=6 active_threads=1 tvp=NULL
conn=1 op=22 SRCH base="dc=ntsp,dc=nec,dc=co,dc=jp" scope=2

Surfers)(|(objectClass=groupofuniquenames)(objectClass=groupofnames)))"

--------------------------------------
are there other things to change aside from the ldap_auth_program line
in my squid.conf file? (i placed there the ldap server's ip address and
search base and i think it is correct)

could it be that there is something else lacking in my config file or
should i change something in my ldap server....

thanks.....
