Joget SSO with Keycloak using SAML

Joget is a low-code no-code rapid application development platform, It’s unique plugin architecture allows one to extend its functionality to any level. Integration with external directory services is one of the key features.  SAML is a general API that most of the directory platforms use to enable SSO. 

Single Sign-On means you can use the authentication from an external platform, It is a really great feature for any Enterprise, While using multiple applications they don’t require their end-user to remember multiple passwords for multiple platforms. 

Keycloak

Keycloak is one of the Directory service providers that have the ability to connect to multiple directory services, It can also work as an Identity Provider.

Integration 

Joget allows integration with any platform using SAML with help of SAML plugin which can be downloaded from the marketplace. Download the plugin and install the plugin in the manage plugins section.
