Microsoft Active Directory Federation Services (ADFS), including:

• ADFS 2.0 (Windows Server 2008/2008 R2)

• ADFS 3.0 (Windows Server 2012 R2)

do not support the SCIM (System for Cross-domain Identity Management) protocol for provisioning users.

What to use instead?

If you want SCIM-based provisioning, Microsoft recommends using Azure Active Directory (Entra ID now), which fully supports SCIM 2.0 for automatic user and group provisioning to SaaS applications like Snowflake, Salesforce, ServiceNow, etc.

If you're stuck on-prem with ADFS and need provisioning, you’d have to:

• Use custom PowerShell scripts

• Or build a custom sync solution via Graph API or on-prem connectors
