Hi,
Thanks for your replies.
I follow the documentation and add a login module option (UserMappinMode = Email) but it changes anything. the login is still not the email address.
Have you ever done that with SAP IDM application?
I suspect that I have to change the configuration file using ConfigTool. I find this blog :
But I don't have the same repository orgnization.. Do you have clues about how do that?
