How to add script mappers to Keycloak: I guess the relevant script mapper needed for vcenter is one to overwrite the sub claim with a user value different from the UUID that Keycloak uses by default as sub claim. The code within the script mapper then is something like this |

I just recently worked this out for my SAML client. I first had to create a script file var user = keycloakSession.getContext().getUser();
var fullName = user.getFirstName() + " " + user.getLastName()
exports = fullNameNext, I created a {
"saml-mappers": [
{
"name": "Full Name Mapper",
"fileName": "full-name-mapper.js",
"description": "Combine firstName and lastName in a single field"
}
]
}Then I had to create a JAR file like this: jar -cvf mappers.jar full-name-mapper.js META-INF/keycloak-scripts.jsonFinally, in my container build I have to copy the jar to FROM quay.io/keycloak/keycloak:26.5 AS builder

Hi Team,
I an trying to integrate keycloak as a OIDC with VMware Vcenter server. I came across one of the blog shared by someone how to do this?
They said I need to create few mappers and one of them is script mapper so wondering how do I create script mapper, In new UI of keycloak I cannot see this mapper?
Do I have to enable some sort of Javascript plugin if yes, how to do it?
Can someone guide me please
