    Replace:

    echo "User authentication unsuccessful";

    with

    echo "Username '{$username}' login failed: ".$adldap->getLastError();

    Result:

    Username 'user' login failed: Can't contact LDAP server

    Info/sources:

    Do a phpinfo() and check where the HOME variable points to in the Apache environment. Create a symbolic link or copy ldap.conf to this location.

    If you get a connect error may be because your local OpenSSL installation doesn’t recognise the certificate (or its authority) provided by the server. This can be circumvented by adding the following line to ldap.conf on your server or similar:

    Change TLS_REQCERT allow to TLS_REQCERT never

    Apache must be able to read ldap.conf, you cannot skip this step.
