[keycloak-user] Use Existing Database without Importing Users

[Marek Posolda]

It depends what exactly you need.
1) There is User Federation SPI, which allows to pull data about users 
from your own database and partially import it to Keycloak. See docs 
http://keycloak.github.io/docs/userguide/html/user_federation.html . 
This SPI allows you to specify which data will be pulled from your DB to 
Keycloak DB, so your store doesn't need to support storing all Keycloak 
user metadata

2) UserProvider SPI - in this case you will need to implement whole 
model by yourself. Note that your store will need to support all 
Keycloak metadata (For example data about user's required actions etc).

For most deployments (1) is better and much easier choice.
