Single Sign On with Sparx Systems ProCloud 3.0 WebEA and Microsoft Server 2016 with Internet Information Server

After an installation as documented with the following User Security settings in Enterprise Architect

SSO 0

You will get the following Login for your model in WebEA – and if you choose to login with Windows ID – the default behavior is that does not work “Internal Server Error” occurs.

SSO 1

Here are the steps to solve that issue

First go to the Web Site’s authentification:

SSO 2

Then change the Anonymous Authentification (WebEA will also work with other authentication modes, but it is not necessary to have the huge overhead for configuring that – as the underlying connection to the data will be authenticated) – The trick is to define the Anonymous user identity as Application Pool Identity.

SSO 3

After such a change it is recommended to restart the Web Publishing Service

SSO 4

Then refresh the Web Site and after choosing the Model and Login With Windows ID – depending on the browser type a Windows Security dialog will occure – here you can type in Domain\User and Password

SSO 5

But be aware of the correct writing – as the user name is case sensitive (EA does not take care, but WebEA does)

SSO 6

Of course in a intranet zone you can get rid of the Windows Security Dialog, by adding it to the Intranet zone via Control Panel

SSO 7

If it is not configured to be automatically detected you can define that manually

SSO 7

With Internet Explorer there is a strange behavior as it does not work properly

SSO 9

So therefore I recommend to use the Trusted Site configuration, but there you have to adopt the custom level to allow automatic login with current user name and password

SSO 10

These settings are used by almost all browsers except Firefox (Firefox always will ask for credentials), whyever – I tried with IE, Edge, Firefox and Chrome.

I am an extrovert promoter and results-oriented controller and director. It like creating new partnerships and relations. I like people that are talking with me and it is important for me to help and motivate others. I'm very self-motivated and I prefer doing thinks I really like. I need a lot of creative and open space. But I also need people doing the administrative tasks and people realizing the ideas.

My highest motivation is doing creative work with and around Enterprise Architect. (www.sparxsystems.de)
