SAP SSO Landscape Deployment

Hi everyone,

I'm after some guidance on the recommended approach (SAP best practice) for deploying SAP SSO Server within our SAP landscape.

We run a 4 system landscape [ DEV -> TEST -> QA -> PRD ] for a number of SAP products (aka ERP, BW ..etc..) and an wondering if you adopt the same approach for SAP SSO Server?

I can't find any documentation that states a recommended approach. The master guide and installation guides talk about the various SSO functions, but don't go into the detail of the System Landscape.

Any advice? Pros/Cons??

Cheers

Shaun
