[keycloak-user] Autheticator configuration

[Branislav Tomko]

Hello

 

I have created a security question Authenticator according Keycloak
documentation by implementing org.keycloak.authentication.Authenticator
interface,

with 2 configurable attributes. 

 

After adding the Authenticator execution into Authentication flow, I can set
initial configuration values for the attributes in admin console (as realm
admin user).

For a first time it's everything OK and the values are set and used during
authentication.

 

But next time, when I try to change the attributes values, I get an
ForbiddenException:

 

14:49:48,783 ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default
task-12) RESTEASY002005: Failed executing GET

Only chance to update attribute values is to remove authenticator execution
from the flow, then add it back and set configuration again "for a first
time".

Any idea why the Authenticator configuration setting works for a first time,
but next update rise an exception?
