Privet, Alexey :) Here's how password reset is done with Keycloak Admin REST API, assuming password policy violation: > PUT http://localhost:8080/auth/admin/realms/master/users/{user-id}/reset-pass... > {"type":"password","value":"foo","temporary":false} < 400 Bad Request < {"error":"invalidPasswordMinLengthMessage","error_description":"Invalid password: minimum length 8."} If I understand correctly, you get a javax.ws.rs.BadRequestException from the Java admin client. You could try calling getResponse().getEntity() on the exception object to obtain JSON response.
