[keycloak-dev] User Federation Provider Cache

[Ariel Carrera]

Hi Marek, Stian, Bill....

I have developed a custom user federation provider. I notice that Keycloak
create several User Federation Providers during a single authentication
flow callin KeycloakModelUtils.getFederationProviderInstance multiple
times...

To prevent create two or three user federation providers per request, I
need implement into my custom Federation Provider a logic for search an
instance of my custom provider into the Keycloak session and if not exists
then create a new one. So... there would be better do it into the method
KeycloakModelUtils.getFederationProviderInstance?

People that implements a custom user federation providers... Do people need
to create multiple instances per request of the same provider?


By the way, I have extended the keycloak SPI to perform use of infinispan
cache when a custom user provider try to validate a user or get some data
from a user federation provider during process. Maybe this could be useful
to other users... if you wants to add this spi, I can try to prepare a pull
request to you.


Thanks
