<div dir="ltr">For the database in a user federation provider you can use <span style="font-size:12.8px">JpaConnectionProvider, but then you have to modify our persistence.xml. Alternatively you can create your own EntityManagerFactory within your UserFederationProviderFactory. Downside to that is that you won't share the connection (and 1pc transaction). We could improve on this in the future as it's a bit clunky.<br></span><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">The other alternative is that we plan to introduce a password hashing spi. With that you can provide the implementation that can hash passwords according to how you have them saved in your current database. Then you can import the users directly into Keycloak and forget about the user federation provider. To import the users you can either export them from your db to a json file (currently you need a full realm file, but we are looking at doing partial import/export now and with that you'll be able to import a json file with users only into an existing realm). Alternatively you can use the rest admin api to import them.</span></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 8 October 2015 at 10:17, Valerij Timofeev <span dir="ltr"><<a
