Some SharePoint 2010 findings


While going through some business requirement analysis for SharePoint 2010 I came across these useful resources that I think are worth sharing as they focus on specific topic’s under consideration.

Sending update Notifications to Email Distribution group

It is possible to send document updates to members of a email distribution list
in two main ways
1) Alerts for the documents and lists, and putting the distribution list and the to source
2) Create a work flow and automate it to send out updates to a distribution list
“Instead of Security Groups, it’s possible to just have some custom SharePoint groups with users in them, and this could be managed by the site admin or individual owners of each group could be given control of their respective groups.  These groups could be referenced in an SPD workflow based off metadata within the submitted doc.  So, let’s say someone submits a doc and selects “Finance” in a department dropdown.  The workflow would kick off, read the Finance metadata from the Department field, and then send the email to the SharePoint Group that you specify for any Finance-related doc.  You’d have to do your mapping in SPD with conditions (If Finance, then send email to Finance Leadership Team).  This is one way to do it without code, but there are other ways.  It just depends on the exact requirements and tools available.”
It is also possible to Sync SharePoint AD Groups with Distributionlist, however not vise versa. http://prequest01.wordpress.com/2008/10/28/send-email-to-all-users-of-a-sharepoint-group/

NTLM Authentication for Java http clients


I was working to provide NTLM authentication to a RSS aggregator plugin http://confluence.atlassian.com/display/CONFEXT/RSS+aggregator+macro+plugin , in our implementation the rssaggregator needed to access rss feed from an IIS installed application within an AD intergrated setup, so our http request needed to go through NTLM authentication.

What I found out during this exercise is that if one is on the same AD domain as the server hosting the secure contents then JDK 1.5 and 1.6 does a transparent authentication at the backend, automatically transferring the login details from the http client to the server , however if the request is being made from a client outside the domain then the login details have to be provided using the username and password for the client accessing the protected resource, for that I found the Jave Authenticator class to be the best option, since you do not have to alter your existing code and just call the Authenticator before the http request and populate the authentication credentials in it. Worked really well for me.
