Gebruikersauthenticatiepatronen voor aangepaste AGOL/Portal-app

Question

Ik ben bezig met het maken van een aangepaste mappingtool voor een klant. Ze willen de standaard AGOL/Portal-app als uitgangspunt gebruiken en enkele van hun eigen aangepaste widgets toevoegen om verschillende bedrijfsspecifieke functies uit te voeren (integratie met andere systemen, aangepaste kaartmarkeringstools, enz.). Ik heb WAB Dev. Edition gebruikt om een testapp te downloaden en enkele widgets aangepast, en deze vervolgens gedeployed naar een interne testserver en alles werkt prima. De testapp gebruikt een AGOL-kaart die met iedereen is gedeeld - dus er verschijnt geen AGOL-loginformulier bij het openen van de lokaal gehoste app.

Mijn vraag(en) heeft betrekking op het creëren van een systeem voor gebruikers toegang tot deze app. Mijn klant heeft een aantal ESRI Named User-accounts, maar ze willen toegang tot hun applicatie mogelijk maken voor 50-100 interne gebruikers. Deze gebruikers zouden toegang moeten hebben tot een aantal lagen en deze lagen kunnen bewerken. Ik heb enkele SDE-featureclasses laten aanmaken binnen de lokale Portal-instantie van de klant (ze zijn gepubliceerd via een gefedereerde ArcGIS Server - dus ze hebben named user-toegang tot deze). Ik heb uitgezocht hoe ik deze lagen kan toevoegen aan de kaart wanneer de app opstart (met gebruik van het named user-account om de lagen te authenticeren), maar dit betekent dat het named user-account moet worden opgeslagen en mogelijk meerdere gebruikers dezelfde named user-toegang gebruiken (wat volgens mij niet in overeenstemming is met ESRI-licenties).

Wat zijn onze opties hier? Staat ESRI-licentie toe om (tijdens runtime) lagen toe te voegen aan een gedeelde kaart die met iedereen is gedeeld? Zo ja, kunnen deze lagen afkomstig zijn uit een SDE-database en gepubliceerd worden via ArcGIS Server? Wat als standaard ArcGIS Server-authenticatie wordt gebruikt vanaf een niet-gefedereerde server? Bijvoorbeeld het aanmaken van gebruikers binnen de ArcGIS Server-gebruikersbeheerhulpmiddel die geen named users zijn.

In principe willen we gebruikers toegang tot de applicatie beheren zonder gebruik te maken van het named user-systeem. Het lijkt technisch mogelijk, maar voldoet dit aan de licentievoorwaarden?

We hebben geprobeerd deze vraag aan onze lokale ondersteuning te stellen, maar hebben nog geen duidelijk antwoord ontvangen.

Thanks, I will look at the video and the pdf.

In our case all users will need to edit, but some of them will only edit infrequently, so level 1 may not be suitable.

Also, another reason for us looking at other authentication methods is we want to provide integration with a non-spatial web application that operates within the clients organization. By integration, I mean things like: user clicks on a spatial feature on the map, which triggers a call to a web service that goes off and finds matching records from the non spatial application based on spatial ID of the feature and returns the matching record(s) which then gets displayed in a custom widget. The existing non-spatial app has its own system of user, roles, groups etc. so we were hoping to be able to use this for the hosted web app, rather than maintaining two systems of users (one owned by non-spatial app and the other being Named Users).

Hi Eugene Lamnek ,

'You can however (as far as I now) add layers on the fly on a Web App that is published on a local web server.'

By local web server, do you mean a web server on the internet as opposed to having the app running from AGOL/Portal?

And do you mean, you can add layers that require authentication, as long as the map is not publicly shared?

It can be a web server inside your own infrastructure or in the cloud, accessible from outside your organization or only available inside your organization. If you download for instance a template application you can modify it or use for instance Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers . What you cannot do is configure an application in ArcGIS Online and share it publicly and consume content that is not publicly available. If you create a webmap in ArcGIS Online and share that publicly, it cannot contain services that are only available behind your firewall. If you add those layers on the fly, the web map on ArcGIS Online will not have any layers that are not publicly available.

With your second point, I understand sharing named users is not allowed. But (my knowledge is limited on this because I haven't tested it) if you are loading layers from a non-federated ArcGIS Server, they would not need to be authenticated by the named user and so no named user sharing would take place??

That may be the case, but if you are going to implement ArcGIS Enterprise, the base deployment (Server, Portal, DataStore and WebAdaptor) will require Federation between the ArcGIS Server and Portal. I think I read this in the slide notes from the presentation on Architecting Your Deployment: See video here: ArcGIS Enterprise: Architecting Your Deployment - YouTube

I will CC Philip Heede hopefully he can clarify this for you.

There is also a great document that might be interesting to read (updated last month): https://www.esri.com/~/media/Files/Pdfs/products/arcgis-platform/architecting-the-arcgis-platform.pdf

Third point, I agree that the named user system would work well, but as the system grows, from what I understand, large costs are involved in having so many named users, many of which may only access the application very infrequently

From "architecting-the-arcgis-platform.pdf ": An ArcGIS Identity is managed as a named user credential within the platform. This credential is used to sign into any app, on any device, at any time, and to provide access to all maps, apps, data, and analysis a particular user is entitled to. As users sign into the ArcGIS platform with their named user credentials, their identity gives them access to authoritative data, GIS capabilities, shared content, apps, and their saved maps and items. The named user model allows an organization to securely and appropriately extend the reach of its geospatial capabilities to everyone who needs them.

So by implementing the named user model, you avoid developing some access to data and applications and you probably miss out on some really good stuff. There are two levels of named users. As far as I understand from your explanation, you will have many users that will simply use the application but not create any content. Those users can use a named user of level 1 which is about 1/5th of a level 2 named user.

Thanks for your comments. Not sure what you mean by your comment:

'You can however (as far as I now) add layers on the fly on a Web App that is published on a local web server.'
