How to use REST between two NEO Java Services

[sienzt]

Hello everybody,

My problem is that I can not authenticate to another java service when using REST. For example, Java service "A" wants to retrieve data from the Java service "B" via REST. Both use the login method "FORM". I am logged into service "A" and service "B" should retrieve and act on my user principal.

How can I authenticate against service "B" with my service "A" principal?

Hello Tom,

the principal propagation between two services A and B can be achieved by utilizing App-to-App-SSO between the two services. By this, you establish a trust relationship between A and B which allows to invoke B considering the principal logged in to A.

Have you looked into that? If so, pls tell us which concrete problem(s) you are facing.

Thanks
