Red Hat introduced the "Zero Trust Workload Identity Manager" (ZTWIM) Operator as a tech preview feature in OCP 4.19, with GA in a future release. This is productized [SPIRE|https://spiffe.io/docs/latest/spire-about/,] a workload identity manager that integrates with Istio.

Istio [documents its SPIRE integration here|https://istio.io/latest/docs/ops/integrations/spire/.]

We should aim to support using OSSM with SPIRE provided by the ZTWIM operator. 

This includes:

• Ongoing regression testing to validate the integration of OSSM + SPIRE
• Any necessary enhancements to make the Sail Operator work with SPIRE (hopefully none)
• Project Documentation for using the Sail Operator with SPIRE
• Product Documentation for using OSSM with SPIRE provided by the ZTWIM operator.

Ideally, this would also include support with Istio ambient mode, in progress upstream:
