Tom has been deep into Web part development the last weeks. Did you know that Tom and Jan are family? So, of course Tom could not ignore the SmartPart (think of the family gatherings these guys have :-)). The outcome is excellent. Tom has created a webpart that allows you to change your active directory password from within Sharepoint. There is a lot of focus on security and since the source code is also available it is a very good sample to learn from. Cool stuff! And excellent contribution to the SharePoint community.
