[Damien]

Thanks qwerty12 and thanks tmsrxzar !
It's working !!
I have created another user and it's working whith this one.
My former user had PasswordResetProviderId set to '' in the database (how ? I don't know) and it seems it is impossible to change it

You should not use the X-Emby-Authorization header as it will be removed in the future: https://gist.github.com/nielsvanvelzen/e...1ffaf12a6f
