 <Message type="important">
   Keep in mind that:
+  - User mapping between Scaleway and the Identity Provider must be done on the user name. When testing the connection, if an error persists about the user not existing in Scaleway, make sure your Identity Provider is mapping the user on their user name
   - Members need to already have been [created manually](/iam/how-to/manage-members/#how-to-create-a-member) in Scaleway to log in.
   - If you delete a user in the IdP, the corresponding Member is not automatically deleted in your Scaleway Organization. The [deletion must happen manually](/iam/how-to/manage-members/#how-to-delete-a-member).
