   There is no more patch

  backport from ERP5

   In past, we used to rely on ERP5 Login (passwordless) for authentication via Certificates, but we switched to use excusively a dedicated portal type (Certificate Login).

   The ERP5 Login now follows the default implementation, so no need custom scripts.

   This helps to figure out what it is really testing.

  Some scripts were removed and on other cases started to be tested.

   After 6 years, it is expected that all instances are migrated. The migration is outdated, since it we use Certificate Login rather them ERP5 Login on Compute Nodes and Software Instances.

    There is no need to pre-create it, since it would be required you go throw External service (Facebook or Google) to create the default connectors.
