This is an example project for using a "Workflow Manager Web Service Activity" with a webservice with basic authentication.
The use of basic authentication is a new feature included in DocuWare 7.1 for the first time.
Current sample is based on the existing sample described here.
In BasicAuthHttpModule.cs on method "CheckPassword" you'll find the current validation for username and password.
Edit this part for your individual needs, e.g. checking with database, ActiveDirectory or LDAP.
