  • A "Label" formatter, with optional link that displays the label of the referenced entity (the node title, the user name, etc.)
  • A "Rendered entity" formatter, that renders the references entity using a configurable view mode
• Integration with Views (for both forward and backward references)

About

This is a very special module and maybe used for only one or a few customers of the company e/t/s (see DLS-link above). But it's a demonstration of a strategy to secure SOAP communications with short time passwords which are pushed into a LDAP database where the DLS Server is checking the passwords from the other side.
For the LDAP operations the API of LDAPcontrol module can be used if installed. With a custom hook the LDAP server controling can be handled on another way maybe with direct PHP LDAP functions.
Additionally some customizing can only be made by hooks in a custom module. And a function to rebuild and/or repair the LDAP data of this module are only accessible with drush: http://drupal.org/project/drush

Features

+ Special short time password handling to secure SOAP communications.
+ Drupal users can join DLS groups by assigning to group nodes.
+ DLS client users are automatic created with joining of a DLS group of its DLS client.
+ DLS access can be handled with content access maybe with organic groups.
+ Single sign on/one time login links as only way to access DLS server vor drupal DLS client user.
