Niet gemachtigd - FME Web Connectie Fout

AdamRepsher

Hallo opnieuw @BruceHarold,

Ik volg je blogpost Een FME Web Connectie maken voor je Enterprise Portal en loop tegen ten minste één probleem aan:

...en in het Vertalingslogboek vind ik dit:

Verzoek om toegangstoken bij te werken mislukt. HTTP-fout: HTTP/1.1 401 Niet gemachtigd - https://myenterpriseportal.org/portal/sharing/rest/oauth2/token

Na het invoeren van mijn inloggegevens krijg ik dit venster...

Ik heb mijn login gebruikt (admin), de login die ik wil gebruiken (een resource-account die wordt gebruikt voor de Enterprise admin-functionaliteit). Ik heb geprobeerd gebruikersnamen op 3 verschillende manieren in te voeren - en het bovenstaande venster toont correct de gebruikersnaam zoals te zien is in Portal.

Mijn Portal-configuratie gebruikt alleen onze Active Directory voor authenticatie en ik heb de Single Sign-On ervaring werkend voor onze gebruikers. Ik sta geen anonieme gebruikers toe en laat mensen geen ingebouwde accounts aanmaken. Ik wijs alleen gebruikerslicenties toe via Active Directory.

Mijn volledige setup...:

ArcGIS Enterprise (Portal, Server, GeoEvent Server) v10.8.1
ArcGIS Pro v2.6.3
Data Interoperability v2.6.2
FME 2020.0.1.0 (20200407 - Build 20218 - WIN64)

Heb je suggesties waar ik moet beginnen met zoeken naar het probleem?

Bedankt,
--Adam

After spending a few days with Customer Service, we have found that there is a bug (BUG-000136812) in my specific situation. I will explain:

My Portal WebAdaptor within IIS is set up with IWA (Windows Authentication) enabled (using Active Directory for accounts and login) AND Anonymous Authentication DISABLED to utilize Single Sign-On. My customers are not prompted for login. They are authenticated with the credentials they used to log into their machine/domain on our intranet.

Workarounds:

Enabling Anonymous Authentication on the Portal WebAdaptor. This is not a solution for me as I want my customers to have the Single Sign-On experience.
Not use the Tools - FME Options - Web Connections for the Portal Connection. Alternatively:
1. Manually set up the connection in a Writer (or Reader), using Kerbos Authentication. (I have not tried this.)
2. Manually set up the connection in a Writer (or Reader), using NTLM Authentication. This has worked for me.

The BUG has already been given a status of Not in Current Production Plan since it is an, "Authentication limitation from a third party component."

I am experiencing the same issue where IWA is enabled and anon disabled.

A potential workaround is the bypass the Web Adaptor and shoot straight to the portal server via port 7443

e.g. https://FQDN:7443/arcgis

If the portal server Fully Qualified Domain Name is myserver.domain.com, then

https://myserver.domain.com:7443/arcgis

make sure you swap out the default /portal in the fme dialog for the /arcgis

If you are running a HA portal environment then just hope the server you select is always up......

hope this helps 🙂

Using NLTM authentication in the writer to create the connection (2b) worked for me. Despite being an admin and signed in via IWA I could not successfully authorise the web service method, likely due to our IIS settings or something in that space. Anyway, thanks Adam for the pointer. I am currently on FME 2022.1.1.0 build 22623 (full application, not interop) and ArcGIS Enterprise 10.8.1.

Question has been moved to the ArcGIS Enterprise space.

No that's us! If you create a support call with Esri it will be officially handled.

I am making a Spatial ETL tool in Pro with the Data Interoperability extension. Sorry for my confusion. Do I still go to their support page?

bharold

The Esri product is Data Interoperability extension which lets you make Spatial ETL tools in Pro, the FME product lives outside Pro. The support channels are separate at the customer level.

AdamRepsher

i'm using FME via Pro....

Same thing?

bharold

Adam if you're using FME the best way to get support is via Safe's support channel.

Chat is very effective as a first step.
