Hello Alfonso Perhaps you found on the net a little documentation about it, i.e. : http://wiki.squid-cache.org/ConfigExamples/Authenticate/Ldap But I recommend you to start learning how to use ldapsearch command by using a simple "man ldapsearch", and also to read about the ldap service. ( ldapsearch command is provided by openldap-client package in a few GNU/Linux distributions) That could help you a lot, because you could retrieve information about the user records on the ldap database, once you know which attributes has a user schema, then you could easily guest what squid is asking about on the squid auth helper. Happy ldap searching Regards RODRIGUEZ Manuel
