I believe I have a sample in the code I put on the WF site. It gets a user then extracts the user's first name, last name, and email address. You can get other details using the helper class I put in the mix.

A good addition would be to get the user's manager. To do so, use the GetADPropertyValue activity and set the LdapPropertyName to "manager". To get a list of direct reports, the LdapPropertyName is "directReports".

Here's a list of some available LDAP properties in AD:

I've emailed the person in charge of the WF part of the site. Send me an email through the contact page (the EMAIL link) and I'll send them to you.
