Re: [keycloak-user] [EXTERNAL] Re: Trust between two standalone Keycloak Instances

Hi Stan, We have 3 enterprise products deployed in their own environments. Now, some of our clients use all three products, some use just one and some use any two of them. Each product is a separate with its own bundled software and not related to the others. So what we want to do is to include Keycloak in each bundle. But there are cases where even from these unrelated products, we need an option for cross product transition.

For that to happen, we need to establish trust between all these separate Keycloak instances. So even if we deploy a new product with Keycloak in its bundle, we would just need to establish trust with the existing system of Keycloak Instances. So is there a way that a token generated by one of the Keycloak instances is accepted by the other Keycloak instances? Also, in domain mode, if we deploy two Keycloak instances separately as master, later if we decide to keep one as master and make the other one a slave, is that possible? And about the local settings, say for example, if I had to connect an LDAP for just one of the hosts, can that be done?

You can also establish trust between two realms on the same server. That way, you don't need multiple instances of Keycloak to have the apps be fully walled off from each other. That being said, I still don't understand why you wouldn't just do it the easy way. Are you saying that sometimes you want SSO and sometimes you don't? I must be missing something from your use case. Lastly, the domain features of WildFly are just used to centrally manage instances of the server. These servers can be configured any way you want. I guess this depends on what you mean by "local settings". On 7/16/2019 1:26 PM, Aditya Bhole wrote: > I understand that deploying 3 clients under one realm will easily enable SSO. Even if we keep the clients in different realms, cross-realm trust can be established. But the use case of our prototype wants the clients to be on different servers.

Sometimes these have to be integrated with each other for seamless cross product experience at which time we would want SSO between the individual product UIs. We intend to use Keycloak as a broker for authentication and to achieve SSO. So that’s why I wanted to know if trust between two standalone Keycloak instances can be established. > > Also, if we deploy the domain controller, can there still be local settings on the different Keycloak instances? > > Thanks, > Aditya > > On 7/15/19, 12:25 PM, &quot;keycloak-user-bounces(a)lists.jboss.org on behalf of Stan Silvert" <keycloak-user-bounces(a)lists.jboss.org on behalf of ssilvert(a)redhat.com&gt; wrote: > > Why do you need each to have its own Keycloak instance?

The use case is that my company has 3 clients; A, B and C. Now each client is going to have its own Keycloak instance; KA, KB and KC. Now what I want is when I login through client A I should be logged into client B and C as well. And same goes for all the clients. So for this to happen, is there a way of establishing trust between these three Keycloak instances KA, KB and KC? > > I’ve successfully established an SSO by using KA as a broker and KB as an IDP. But this is only a master slave kind-of an architecture. When I log in to A, I’m automatically logged into B. But if I log into B, I won’t be automatically logged into A. Is it possible for KA to be a broker for KB and KB to be a broker for KA at the same time? > > TL;DR : > > Is there a way where Keycloak only acts as a broker and trust is established between multiple such Keycloak instances? > > > > I hope my question makes sense.
