Padrões de autenticação de usuário para aplicativo AGOL/Portal personalizado

Question

Estou investigando a criação de uma ferramenta de mapeamento personalizada para um cliente. Eles gostariam de usar o aplicativo padrão AGOL/Portal como ponto de partida e adicionar alguns de seus próprios widgets personalizados para realizar várias funções específicas de negócios (integração com outros sistemas, ferramentas personalizadas de marcação no mapa etc). Eu usei o WAB Dev. Edition para baixar um aplicativo de teste e personalizei alguns widgets e depois implantei isso em um servidor de teste interno e tudo funciona bem. O aplicativo de teste usa um mapa AGOL que é compartilhado com todos - então nenhum formulário de login AGOL aparece ao entrar no aplicativo hospedado localmente.

Minha(s) pergunta(s) refere(m)-se à criação de um sistema de acesso do usuário para este aplicativo. Meu cliente possui várias contas ESRI Named User, mas eles gostariam de permitir o acesso à sua aplicação para potencialmente 50-100 usuários internos. Esses usuários precisariam acessar várias camadas e poder editar essas camadas. Eu fiz algumas classes de feição SDE serem criadas dentro da instância local do Portal do cliente (elas foram publicadas via um ArcGIS Server federado - então têm acesso via named user a elas). Eu descobri como adicionar essas camadas ao mapa quando o aplicativo inicia (usando a conta named user para autenticar as camadas), mas isso significa armazenar a conta named user e potencialmente permitir que vários usuários usem o mesmo ponto de acesso named user (o que eu acho que não está em conformidade com a licença ESRI).

Quais são nossas opções aqui? A licença ESRI permite adicionar (em tempo de execução) camadas a um mapa compartilhado que é compartilhado com todos? Se sim, essas camadas podem vir de um banco de dados SDE e ser publicadas via ArcGIS Server? E se for usada a autenticação padrão do ArcGIS Server a partir de um servidor não federado? Ou seja, criar usuários dentro da ferramenta de gerenciamento de usuários do ArcGIS Server que não são named users.

Basicamente, gostaríamos de gerenciar o acesso dos usuários ao aplicativo, sem usar o sistema named user. Parece que isso é tecnicamente possível, mas está em conformidade com a licença?

Tentamos fazer essa pergunta ao nosso suporte local, mas até agora não recebemos uma resposta clara.

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.'
