Hello! I have same problems configuring Alfresco repository. It is configured with external Cas Authentication.
I configured repository api url https://www.alfresc.com/company/sales/alfresco/api
When I try upload file, moodle ask for user and password (alfresco repository) and sends to api uri.
I think this plugin is not ready to validate Cas user.
Is this true??
Thank's for all.
