[keycloak-user] Set up user attributes at account creation

[Rémy Grünblatt]

Hi,
Is there any possibility to automatically set up attributes (such as an
unique integer Id) at account creation, with keycloak?
I'm trying to set up a "rank" (1 for the first user, 2 for the second
user, 3 for the third one) as an attribute and I'm having trouble to
find out how I could « automate » this.

Thanks,
Rémy
