Dear all,
Is it possible to use a different discovery service depending on the SP
that sent a SAML AuthnRequest to SATOSA, or do I have to do that in the
discovery service's frontend somehow?
Best wishes,
Matthew

Hi all,
I want to include a KeyDescriptor for use=encryption in the generated
SAML2 metadata. I'm talking about the
{host}/Saml2/proxy_saml2_backend.xml endpoint.
The following config works (i.e. SATOSA happily accepts encrypted
assertions), however the metadata endpoint does *not* include
use="encryption":
sp_config:
key_file: /etc/satosa/credentials/saml2backend.key
cert_file: /etc/satosa/credentials/saml2backend.crt
On the other hand, the following config does not work (i.e. SATOSA
throws an exception, once an encrypted assertion is received), however
the metadata endpoint *does* include use="encryption":
sp_config:
key_file: /etc/satosa/credentials/saml2backend.key
cert_file: /etc/satosa/credentials/saml2backend.crt
encryption_keypairs:
- key_file: /etc/satosa/credentials/saml2backend.key
cert_file: /etc/satosa/credentials/saml2backend.crt
I'm sure there's an easy solution. Anyone able to help?
Cheers,
David
I am trying to put this proxy solution in place in order to provide support for the REFEDs MFA profile. Here is what I want to implement:
1. SP sends Auth Req to Satosa front end with REFEDs MFA profile ACR
2. Satosa makes a routing decision based on existence (or not) of the MFA profile in the request
3. If MFA profile exists, forward requests to IDP 1. Otherwise, route to IDP 2.
4a. Routing to IDP 1 for MFA makes an assumption that MFA was performed and then inserts the MFA profile into the returned SAML response
4b. Routing to IDP 2 for non-MFA makes an assumption that MFA was NOT performed and does not modify the response
5. The Satosa front end returns the assertion to the SAML SP
I'd like this routing to be dynamic based only on the existence of the MFA profile in the request without having to maintain a static mapping of SP entity IDs.
Reviewing the code, it seems like this might be possible in the DecideBackendByRequester micro service, however the functionality there is based on a static lookup table of entity IDs.
A dynamic routing might be possible with a similar approach if one is able to obtain the ACR from the request context decorators. Is the ACR information added to the request decorator (internal_data) when the inbound request is processed?
Does this seem like a reasonable approach to the problem?
Thanks,
Jim
Hello,
I’m hitting a strange problem; when a successful SAML response is received by the Satosa backend containing a pretty complete attribute statement (see below), the attributes not recognised by the Backend and I see the error “backend received attributes: {}”.
I’m currently just testing things and haven’t changed the internal_attributes.yaml from the example. My IdP is currently just the SimpleSAMLphp userpass example with some mocked up SAML attributes. I wondered whether the attribute Name Format is incorrect, but I don’t see where this can be configured within Satosa.
Has anyone else hit this problem?
Thanks in advance,
Hannah
