Web applications that need to access services protected by a user's Google or Google Apps (hosted) account can do so using the Google Authentication service. This service lets web applications get access without ever handling their users' account login information. Many but not all Google services support the Authentication service; check first with the service you want to access.
Google offers two libraries for handling authentication: one using the OAuth open standard, and a second interface called AuthSub, developed prior to the release of the OAuth standard. This module implements the AuthSub interface.
OpenID Content Profile Field maps OpenID AX/SREG fields to node fields. It can be used either on an OpenID relying party (client) or an OpenID provider.
Slideshare slides can thus be embedded in any content type with an Embedded Video Field by pasting the URL of a Slideshare presentation into that field.
This module provides both a thumbnail and a Flash embed representation of the presentations, and provides support for listings via Views module.
Requirements
The Embedded Media Field module and its dependency, CCK (content.module) must both be installed and enabled, as must the Embedded Media Field sub-module Embedded Video Field.
You must acquire a free Slideshare API in order for the embedding to function.
This module allows access to nodes with attached and related files, as well as access to file node contents, via a WebDAV metaphor similar to File Server. The user can browse all files existing in the system by file MIME type, attached- or related-to node type (e.g., event, story, etc.), and attached- or related-to node parent group. Group browsing additionally supports OG Vocabulary integration, which browses by group taxonomy to find attached- or related-to nodes.
