Workflow Soluiton

There are three different methods you can use to Authenticate a User in Workflow.

1) Utilize IIS to authenticate a user for you.  This is one of the best and easiest methods to authenticate a user in a workflow process, it acts as a "single sign on" if the user is on their network and already authenticated to the domain.  Follow this link explain how to use IIS as your authentication method:      http://www.symantec.com/docs/HOWTO9280     

2) Use one of the login form builder components.  There are a couple of pre-configured login form builder components that you can utilize as the first in a series of webforms (these can also be used inside a Dialog Workflow component).  Some of these forms will allow you to create a timed cookie to make it easier for users who are working with several Workflow process sessions within a short amount of time.

3) Preform a Password Check via a Token.  In some cases you may not want to utilize IIS or one of the Login Forms, for example to use as part of a 'Digital Signature'.  Unfortunately, there currently is not a "test password" component outside of a login form, but you use the Domain, Username and Password in the "Create Basic Authentication Token" component.  Then use that token to preform some kind of network action, for example access a SQL table or a Share Folder, in this method you can test the validity of the token which intern will test the password.
