I have worked with SAML in combination with Tableau and my experience was the following:
Tableau Server was enabled with SAML and worked in combination with Oracle Identity and Access Management.
The company had multiple applications but didn't really want a seperate login screen for each of the applications.
That's where IAM came in place, when you entered the URL of an application you were forwarded to the login page of IAM.
In case your credentials were correct and you were a user of the underlying application the access was granted.
So I enter the URL of my Tableau server. The first thing I see is a login screen not belonging to Tableau Server. After I've provided my credentials I can be forwarded to Tableau Server.
I hope this made it a bit more clear.
Here we are not using oracle identity access management . i am here trying to understand the SAML in layman terms . like who is Service Provider and who is Identity provider.I am looking for an example which is practically easy to understand
I will try to explain it with the same setup again but with the terms of Service Provider and Identity Provider.
1. I enter the URL of my Tableau Server (Service Provider)
2. Tableau receives an access request and is going to forward it the the Identity Provider. In my case this is the Oracle Identity and Access Management option
3. This Identity Provider is going to request my username and password
4. The Identity Provider sends a SAML SUCCESS to the Service Provider (Tableau)
5. The user gets access to the Service Provider
Hope this makes it more clear !
This is helpful but i have one doubt. Suppose if i am not using Oracle identity and Access Management are there others Identity providers available or the one which you have mentioned is the only identity provider because i am not aware of the backend process how SAML works internally. Initially i was thinking of Identity provider was of company Active Directory which will authenticate users and send the request back to Service provider. to give access to the tableau server.
One more thing how can i check which identity software management suite my company is using for SAML ?
It's perfectly possible to use your Active Directory in combination with Tableau Server, but no SAML is required to set this connection up.
SAML is used with a seperate access manager besides your Active Directory.
