Hello 😊

I recently updated FME Form to version 2026.2 and started experiencing an issue when connecting to an Enterprise Geodatabase using an SDE connection file configured for Operating System Authentication.

FME returns the following error:

"Failed to connect to Enterprise Geodatabase using connection file 'path_to_the_sde_file' due to missing credentials. A connection requires either Windows Authentication or both a user name and a password."

The SDE connection itself appears to be valid. If I open the same .sde-file in ArcGIS Pro, it connects successfully and shows the correct authentication type in the connection properties.

This workflow worked without any issues in previous FME versions and only started failing after upgrading to FME Form 2026.2.

Has anyone encountered this problem before? Is this a known issue in 2026.2, or is there a workaround available?

Any help would be greatly appreciated.
