Hello,

I need to call an external WS in soap from an Ignition gateway script.  
the authentication of the WS is in NTLM so with active directory, which user will Ignition use to perform the call? the one that is running the Ignition Service?  
Is it possible to call the WS by changing the user credentials in the script?

many thanks  
Andrea

I’ve never noted anyone getting this to work. The only comparable action is SQL Server auth, but that requires a special DLL just for that purpose, and only works if the gateway is on Windows.

Plan on getting that service to allow conventional credentials, or an API token system.
