thanks for your help.
1. Version is currently 3.1.6
2. yes, automatic redirection is in place and works properly!
Let me try to explain what problem I am facing:
Due to some error (I was not able to trace it) the automatic redirection did not work. My guess is that the saml server was not able to connect to the remote IDPs and could not load the strategies.
In such a case the passportlogin page is being shown for dedicated provider selection. We are using inbound saml and I must somehow avoid the display of the external providers. Customers should never see other customers IDPs.
All the best,
