Thanks. I’ve a little bit of experience with Fedora so i ‘ve created a VirtualBox machine and I’ve installed a Fedora Core 18. I’ve installed squid (yum install squid) ; I modified squid.conf with external helpers (squid_ldap_auth and squid_ldap_group) but the service squid fails because there’s no squid_ldap_auth (or group) in the folder /usr/lib64/squid. I think squid comes with no ldap helpers and so I must recompile it but I don’t know how. Squid version is : rpm –q squid squid-3.2.13-1.fc18.x86_64. As I said I think squid must be recompiled with options to enable external-helpers; if this is the problem, how can I implement this features ? I read something about it ; download the source of squid and then (after execute tar command) execute ./configure –helpersoption and finally make install but I’ve no experience about this. Can someone help me ? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Issue-with-Squid-ldap-group-Windows-tp4663221p4663367.html Sent from the Squid - Users mailing list archive at Nabble.com.
