[keycloak-user] Update user attributes on login

[Oliver-Rainer Wittmann]

Hi,

I have a running keycloak with a custom identity provider - corresponding implementation of AbstractOAuth2IdentityProvider

On registration of a user certain user attributes are stored and mapped into the token.
Now, I want to update these user attributes on following logins.

How to do this?
Unfortunately, I did not find a corresponding hint in the documentation.

Thx in advance for your support.

Best regards, Oliver
