Alfresco JS API Authentication Options

[chao]

Is there another option for ECM/BPM authentication without using username and password in the Alfresco Javascript API? Assuming the user is already authenticated through external identity access management system, is there API endpoint to retrieve API token for both ECM and BPM?

If you are already auth you can just get the instance and perform the calls

Thanks for the reply. What I mean is the user is authenticated for the ADF web application, but not authenticated to ECM/BPM.

Sorry, is not clear to me the difference. The only authentication that ADF can perform is the one against BPM and ECM or both.

Let's say the ADF web app is protected by IAM, a user logins through external custom interface, then redirected back to the ADF home. How does ADF in this case authenticate against ECM/BPM REST API without using username and password?
