I am in the process of deploying a new GIS platform (~250 users) and need FME Form to connect to branched versioned feature services hosted in our ArcGIS Enterprise Portal 12.0. When Integrated Windows Authentication (IWA) is enabled on the Portal (to allow seamless sign‑in on the network), FME cannot authenticate the web connection.
Environment / what works vs. fails:
- FME Form reader: Esri ArcGIS Feature Service
- FME Web Connections tried: Esri ArcGIS Enterprise OAuth and Esri ArcGIS Portal token
- Both succeed when IWA is disabled
- Both fail when IWA is enabled (FME can’t establish the Portal connection)
Goal: Ideally keep IWA for user convenience and allow FME to run reconcile/post workflows against branched feature services. If the only practical path is to have users sign in and “remember credentials,” we can accept that, but I am hoping for a better solution.
Questions:
- Does FME Form support connecting to Portal secured with IWA, and if so, what specific Web Connection setup is required?
- Are there known workarounds (e.g., alternate Web Adaptor/Portal auth provider for service accounts, OAuth app registration settings, proxy headers, or FME-specific/portal setting configurations) that let FME authenticate while IWA remains on?
- Any best practices for FME against branched versioned services under IWA (service accounts vs. named users, token lifetimes, scheduled automations)?
Appreciate any insight, examples, or docs others have used to make this work. Thanks!
