Multiple ACSs URL

[aasifalam]

I am trying to evaluate python-saml for enabling our SP with SAML functionality.
How do I keep track of the AuthnRequest for each login request ?

1. Can I send ACS url in AuthnRequest..perhaps append each ACS url with unique Id ? The id later can be looked when IDP sends the response to figure for which login request this was for ?

2. Or if I could add some index number in the AuthnRequest sent, which I can later match in the response message recevied back from IDP ?

I was looking up the API description and could not find much help there.
Appreciate if someone can help me with example code.

Thanks
Asif

I recommend the id approach if you connecting with multiple IdPs, so you can create a connection:
SP id --> IdP.

The 2nd approach is when you want to support ACS URLS with different bindings, in that approach you may define on SP metadata several ACS URLS. (but this toolkit supports only ACS URL HTTP-POST binding.

Do you plan to support other bindings for this toolkit in future ?
We expect multiple IDPs. However at the SP side I wanted a reliable way to map the IDP response with the user requesting the login.
For this wondering if I could use the IDs for this ? I am using flask for session management.

We don't plan to officially support ACS HTTP-Redirect binding.
In #71 was implemented that functionality so you can review and add it to your python-saml project if you interested.
