When using a user with a capital letter, the plugin authorization (at least for admin rights) is not working as expected:
- for the UI it requires to use the exact case
- for the API it requires to use lower case
Workaround: add the user two times, once with the exact case a second time lower case.
Eg, in my case my user is PierreBtz, the admin user name is: PierreBtz, pierrebtz
