[squid-users] acl problem (Amos Jeffries)

Thu Aug 31 12:44:46 UTC 2017

Thanks for answering Mr. Jeffries, I just applied his recommendations, I 
changed the "allow basic_ldap_auth" rule to "deny! Basic_ldap_auth", I 
also left the acl names denied and removed their respective "acl deny 
rule" and the rule "http_access deny I left it on the last line. 
Although I did not give problems the "squid3 -k parse". But the link to 
the ldap suddenly stopped working, searching at 
"http://www.squid-cache.org/Doc/config/" I saw that I had to change the 
parameter "external_acl_type Group" to "external_acl_type ldap_group" . 
The Ldap user password has not change and there are other applications 
that are using the ldap correctly at this time, any sugestions?

Here is a copy of my current configuration file
