Ray,
if I understand this correctly, the MENU and other methods only
present (or select from) IdPs explicitly defined and configured in CAS
properties? Meaning, if we configure single delegation to SAML2 IdP and
point it to metadata of all our federation IdPs, only the first IdP is
used by CAS server and only the first one is presented by CAS internal
MENU discovery method, right? And should we need to delegate to more
federation IdPs, all of them must be added to CAS server properties?
Regards,
Michal V.

wouldsmina,
Are you getting a menu of IdPs to select from, or does cas always
default to cas.authn.pac4j.saml[0]
At the bottom of the cas doc page are a set of tabs 'MENU', 'DYMANIC',
'CUSTOM'. Dynamic has example JSON. If you want a menu, you could try
creating a list of IdP entityId's in a JSON file. (We are only
beginning with using cas for SAML, so I am doing a bit of guessing.)
RequestInitiator is optional, you can remove it from metadata.
SP do not usually need the signing cert.

I've tried configuring all the IdPs with the same values (as in the
example), but only the first one used works. In the metadata file
generated by CAS, I find data specific to the first IdP:
<init:RequestInitiator
Binding="urn:oasis:names:tc:SAML:profiles:SSO:request-init"
Location="https://auth.icoopeb.org/cas/login?client_name=*lmu*"/>
CAS also generates the saml-signing-cert-*lmu*.crt
saml-signing-cert-*lmu*.key files, but I don't think that's a problem.
Thanks for the link, I had seen this documentation, but I don't
understand what the json file of
cas.authn.pac4j.core.discovery-selection.json.location should contain.
Is there any documentation or an example ?
Wouldsmina.

Yes.
There is a section on IdP selection,

Hello Ray,
Thanks for your reply.
Here is an example of what I did:
cas.authn.pac4j.saml[6].keystore-password=password1
cas.authn.pac4j.saml[6].private-key-password=password2
cas.authn.pac4j.saml[6].service-provider-entity-id=https://auth.icoopeb.org/cas/sp/ufra

If I understand what you're proposing, I have to do this:
cas.authn.pac4j.saml[6].keystore-password=password1
cas.authn.pac4j.saml[6].private-key-password=password2
cas.authn.pac4j.saml[6].service-provider-entity-id=https://auth.icoopeb.org/cas/sp/all

cas.authn.pac4j.saml[6].logout-request-binding=
cas.authn.pac4j.saml[7].keystore-password=password1

Wouldsmina,
Once your SP metadata is in the specified location, cas will
not recreate it.
Are you using a different entityId or key for each IdP? That
is not necessary.

Hello,
I want to use identity delegation to allow other IdPs to
authenticate a number of my services. I was inspired by this
documentation:
https://fawnoos.com/2023/10/04/cas66-delegate-authn-saml2-idp/.
But I notice that for each declared IdP, CAS produces
different EntityId and metadatas.
The IdPs concerned are part of the EduGain identity federation
and I'd like to declare a single SP (for simplicity and to
comply with the charter). Do you know if it's possible to
configure CAS to create a single EntityId for all declared IdPs?
Best regards,
Wouldsmina
