Support » Plugin: simpleSAMLphp Authentication » Setting up simpleSAMLphp Authentication plugin

  • Resolved dizzystreak



    I am trying to get the simpleSAMLphp Authentication plugin 0.4.0 working with WordPress 3.0.5 (network mode). SimpleSAMLphp is configured do use our LDAP server directly.
    There are a few snags I’ve hit.
    After a default install and brief setup of the plugin, I get this error:

    PHP Warning:  Parameter 1 to SimpleSAMLAuthentication::authenticate() expected to be a reference, value given in /.../wordpress_3.0.5/wp-includes/plugin.php on line 166, referer: http://site.wordpress.FQDN

    After changing
    function authenticate(&$username, &$password) {
    function authenticate($username, $password) {

    Then, clicking “Log In” takes me to a simpleSAMLphp login, and I get successfully authenticated by LDAP and then it fails, because there is no returnTo link offered to simpleSAMLphp.

    Is there anyone, that has successfully made this plugin to work ?

  • For this plugin to actually work I had to do the following modifications:
    – $_REQUEST[‘redirect_to’] seems to be empty when plugin tries to set the ReturnTo argument for function at line 98. So i changed that line to:
    $as->requireAuth(array('ReturnTo'=> get_option("siteurl")."/wp-admin")); # $_REQUEST['redirect_to']));

    – at this point the login was working for users which already existed in WP db. But when the user does not yet exists this plugin tries to manually add the new user. The problem is that $attributes['email'] is empty. So I did a var_dump on $attributes and found the right email field which is $attributes['mail'][0].

    – add return new WP_User($wp_uid) at the end of “// auto-registration is enabled” if clause

    We are using WP 3.0.5 and SimpleSAML 1.6.2

    Thanks brkt.
    I tried it with WP 3.0.5 and SimpleSAML 1.6.3.
    It worked, after I removed the ampersands from
    function authenticate(&$username, &$password) {

    whoops, why can’t i delete a post i posted in the wrong spot? heh heh, what’s up y’all.



    0.5.1 with brkt’s fix seems to resolve our problem.
