>For now, for testing purposes we are going to add users to Gluu Server manually utilizing Gluu Server LDAP how mentioned in the Local User Mangement document here: https://gluu.org/docs/ce/user-management/local-user-management/
Ok, that's fine.
>We are going to integrate our 2 web applications; one server side application (webservice); 5 3rd party applications installed in separate machines but in the same VPC (Dataiku, Tableau, RapidMiner, H2O, RStudio). I was not able to find any documentation in your documentation section regarding these tools integration.
I don't think we have documentation specifically for those tools, indeed. It's hard to cover all possible 3rd-party software, and usually a new article like this appears as a result of integration project done per a customer's request, unless this particular service looks very promising and somebody on the team has some free time to spend on a test setup.
> All mentioned 3rd party tools installed in AWS in separate machines (EC2 instances). Should i use Single Sign-On (SSO) to Amazon AWS document, which is here https://gluu.org/docs/ce/integration/saas/aws/ ?
This guide allows your Gluu instance to handle authentication when somebody accesses AWS management web console, I believe. If this will satisfy your needs it's worth a try.
>We are going to use OpenID Connect, so I will go and review mod_auth_openidc RP Integration document. I think in this case I don't need to do any code changes in our web applications as we will use reversed proxy. Am i right? If not, please point me to the right document, which describes what I have to change in our code in case of web application and server side service.
Apache can handle authorization for you, if that's what you had in mind. After receiving user's personal data from Gluu, you can employ something as simple as this:
```
<Location /secure>
AuthType openid-connect
Require valid-user
</Location>
```
...or use more sophisticated rules to control which user can access what. This again is a bit beyond scope of Community Support and belongs more to Apache's related forums/mail lists.
