[squid-users] Custom external acl helpers in PHP

[Walter (NIF)]

Hi! I wrote a PHP script to authenticate users in a postgresql server 
and it's working perfectly.

The question is that we have some groups with different privileges. We 
had a LDAP base where
the users were authenticated with the ldap_group external acl. I'd like 
to write my own external
helper in PHP but I don't know how to make it get the current logged 
user and the group set in
the acl like:

acl students external ldap_group students

Thank's in advance!
