Hi, I've just compiled the latest stable release of squid (Ver 2.5 release 14) in order to test out the ldap authentication with samba ver 3.0.22 when I try to run the squid_ldap_group application to test it's working I get an error: "./squid_ldap_group: error while loading shared libraries: libldap-2.3.so.0: cann ot open shared object file: No such file or directory" The file does exist in the following location: /usr/local/lib/libldap-2.3.so.0 I think it might be an environment variable that I need to set such as LD_LIBRARY_PATH ? Could anyone advise ? I'm using RHEL4. I compiled squid using the following swicthes: ./configure --prefix=/usr/local/squid --enable-auth="basic,ntlm" --with-external-acl-helpers="ldap_group" I then did a "make" and "make install" in the ./squid-2.5.STABLE14/helpers/external_acl/ldap_group/ folder to install the helper on the system. thank in advance PD
