IBM Worklight 6.1 - connectAs endUser before authentication

I have a question about the connectAs="endUser" option, found in the adapter XML file.

In the design mode I can read

   - endUser: The connection to the back end will be created with the user's identity, as authenticated by the authentication realm

So my question is: Does it have sense to use the option connectAs="endUser" without being authenticated and without defining a security test?

I am having this question, because I used to put the connectAs="endUser" in the authentication procedure

<procedure name="authenticate" connectAs="endUser"/>

Is that wrong?

So as you can see in the documentation using connectAs="endUser" is "Only valid if a user realm has been identified in the security tests for this procedure."

Here are some resources you may want to look into:

Can you please provide your scenario to how you would like to use this setting in greater detail
