# ldap_bind

(PHP 3, PHP 4 )

ldap_bind -- Bind to LDAP directory

## Description

bool ldap_bind ( resource link_identifier [, string bind_rdn [, string bind_password]])

Binds to the LDAP directory with specified RDN and password. Returns `TRUE` on success or `FALSE` on failure.

ldap_bind() does a bind operation on the directory. `bind_rdn` and `bind_password` are optional. If not specified, anonymous bind is attempted.

Example 1. Using LDAP Bind
    <?php

    // using ldap bind
    $ldaprdn  = 'uname';     // ldap rdn or dn
    $ldappass = 'password';  // associated password

    // connect to ldap server
    $ldapconn = ldap_connect("ldap.example.com")
        or die("Could not connect to LDAP server.");

    if ($ldapconn) {

        // binding to ldap server
        $ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);

        // verify binding
        if ($ldapbind) {
            echo "LDAP bind successful...";
        } else {
            echo "LDAP bind failed...";
        }

    }

    ?>

Example 2. Using LDAP Bind Anonymously
    <?php

    //using ldap bind anonymously

    // connect to ldap server
    $ldapconn = ldap_connect("ldap.example.com")
        or die("Could not connect to LDAP server.");

    if ($ldapconn) {

        // binding anonymously
        $ldapbind = ldap_bind($ldapconn);

        if ($ldapbind) {
            echo "LDAP bind anonymous successful...";
        } else {
            echo "LDAP bind anonymous failed...";
        }

    }

    ?>
