Hi Amos, I'm not sure I understand what you mean. Should those commands not work when run by themselves from the linux shell? When I put the LDAP config in squid.conf I get these lines in cache.log everytime I attempt to log in from a browser: basic_ldap_auth.cc(740): pid=1982 :attempting to authenticate user 'uid=USERNAME,dc=DOMAIN,dc=com' The log in fails, but nothing else is logged. ---------------------------------------- > Date: Tue, 28 May 2013 00:01:22 +1200 > From: squid3@xxxxxxxxxxxxx > To: squid-users@xxxxxxxxxxxxxxx > Subject: Re: ERR Missing username using basic ldap auth > > On 27/05/2013 1:10 p.m., Nathanael Chambers wrote: >> Hi, >> >> When using the basic_ldap_auth helper (compiled with squid 3.3) I get the an error saying "ERR Missing username".
