[keycloak-user] Get Keycloak to include AttributeConsumingServiceIndex in SAML2.0 AuthnRequest

[Georgi Matev]

We are using Keycloak as identity federation gateway, and one of the IdPs we are trying to connect to requires that SAML requests specify a AttributeConsumingServiceIndex so that the desired requested attributed can be returned.

Have not been able to find a way to specify the index vlue so that the AttributeConsumingServiceIndex can be included in the request as part of configuring a SAML provider under Identity Providers.  Any recommendations on how to configure this?

Thanks,
