/* Authentifizierung des User */
if (($link_id = ldap_bind($connect, $user_dn, $password)) == false) {
print "failure: username, password didn't match: $user_dn<br>\n";
return false;
}
return true;
@ldap_close($connect);
} else { // no conection to ldap server
echo "no connection to '$ldap_server'<br>\n";
}
echo "failed: ".ldap_error($connect)."<BR>\n";
@ldap_close($connect);
return(false);
}//end function checkldapuser
Here a sample for using this function:
if (checkldapuser('myuser', 'secretpassword', 'ldap://link.to.ldap'))
{
echo "ACCESS GRANTED\n";
} else {
echo "ACCESS DENIED\n";
}
