The entire chain is shipped with the EAP handshake (I know, not ideal), but
the ultimate root *should* suffice.

I refer to this part in the IdP guide (verbatim):

"For most EAP methods, the required EAP details are
The Certification Authority (CA) certificate(s) which signed your EAP server
certificate
always include the root CA (root CAs are indicated with a blue circled "R"
besides the certificate details after upload)
optionally include intermediate CAs (intermediate or server certificates are
indicated with a blue circled ("I") besides the certficate after upload)
The name of your server as specified in the Common Name (CN) of your EAP
server certificate"

I've done a check and yes, the CA root cert on the server and the CA root
cert on CAT match (as per Martin), and openssl verifies the chain ok:

[support:~] openssl verify -CAfile bspa-root.crt -untrusted bspa-interm.crt
bspa-srv.crt
bspa-srv.crt: OK

So no, it's not the chain, because actual authentications would have failed.

Hi,

Ah, in that case it looks like the intermediate certificate is missing?
This contains just the/a QuoVadis root.

Thanks for checking on the profile, I didn’t get to that yet,

(I doubt this profile works well in CAT?)

Regards,
Paul
