For web applications in the external IAM, it can easily be implemented with the Keycloak extension mentioned above. The required authorisation management function comes from the internal IAM and ensures clarity in the delegation and allocation of roles for specific users. However, there is a smart solution for this mammoth task: the authorisation framework SecuRole® avoids unnecessary realm proliferation. It is determined by the organisational structure to be mapped or the requirements of user groupings. The user landscape determines the complexity of the Keycloak realmsĬomplexity is already there from the beginning. Numbering is also possible: “Realm 1”, “Realm 2”, etc.įind out how to configure realms here: Configure realms in Keycloak It makes sense to give the realm a meaningful name, such as “Customers”. First, you work with the “master realm”, from which you set and control the other realms. The addition of several realms should be carefully considered and planned. To integrate an application in several realms, it is often necessary to use an additional instance of that application. Applications can usually only be integrated in one realm.One or several Identity Providers (IDPs) can also be included, who can be directly integrated in one or more realms.In a group, individual roles can be summed up and, in this case, a group represents a set of users who have these roles. If this login is to run via Keycloak, this simple role must be defined in the Keycloak realm.Īn application role is a set of permissions for the associated application. At first, only a default role is of interest, which allows a user to access his or her account after registration. Here is an example that isn’t too abstract: The widely used Atlassian software, which provides tools for developers, makes use of different roles for its users. Roles supplement the model: they can be assigned either to a single application or an entire realm.the assigned applications to which access is granted (single sign-on). Data and configurations are stored in it, and they are not visible to other realms. In Keycloak, each realm is like its own client, which is why we also speak of multi-tenancy or multi-client capability. The use of too many realms results in too much complexity
