Basic Authentication with the

...

Bridge

To implement basic authentication with the bridge one has to define the two tagged values authenticationMode and user in the component diagram. By setting these two tagged values this service can only be called when this user and its password are set in  the SOAP or HTTP header.

The above example shows how to implement basic authentication executed directly at the E2E Bridge. This implementation supports only one user. So one can define only one user at the "user" tagged value. This is suited for simple implementations or for testing. When having the need of supporting more than one user or have the user definitions stored in a external system like LDAP then one must define a proxy in front of the SOAP/HTTP service.
This example shows how to call such a service which requires basic authentication.

In chapter Adding Role Using Preprocessor the role have been assigned statically which in real world project would not be the case. The roles will be stored in a databases, LDAP, ActiveDirectory, a file or any other system. So the user will be given from outside through the SOAP or HTTP header by applying basic or secure authentication. The user is mapped by the E2E Bridge to the user attribute of The Principal Object .
