Hello Ridouan,
Thanks for your reply.
Users have been imported from SAP and I don't want to oblige them to change their password, so they are still working with the password the set in SAP before.
I just would like to avoid password de-activation when I add the business role, maybe it's not trigerred, but I think well.
Self-service for reset password works, I don't think it's related to de-activation.
Nicolas.
