Hello! First of all thanks for the provided code, I have a question, is there any official documentation of how to use the
org.keycloak:keycloak-admin-client ??

For sure your example is great but if I hadn't found this, it would be a nightmare to learn how to use it on the fly.

@thomasdarimont Isn't it possible to do it in one shot? Assign password and roles when creating the user? I tried but it seems not to work...

nope! I was trying to do the same thing. It looks like keycloak update only the user entity and any children (like credentials) remains untouched. Il giorno mar 30 gen 2024 alle ore 14:12 ghilainm ***@***.***> ha scritto:

@AndreaNicola Credentials seem to work for me!

Hello, how do I use keycloak for its new versions?

If you still getting "HTTP 400 Bad request" error after following the tips and hints in this ticket or it suddenly stopped working, make sure the user account you are using does not have unresolved required actions such as verify email, fill in first name and last name etc. because you can't invoke direct grant if there are unresolved required actions!

I am using the latest version (24.0.3) at the time of writing this comment.

@maj2c Yes! That was it! Since the Firstname and Lastname fields are not marked as required in the Keycloak UI, I didn't bother filling them in. And, testing shows if either of these are missing it throws a 400! I think that is probably a bug? No?
