University of Aberdeen

Shibboleth SAML Identity Provider (UK Access Management Federation)

The University's own Shibboleth Identity Provider, entityID https://shibserv.abdn.ac.uk/shibboleth, asserting shibmd:Scope abdn.ac.uk. Its entity descriptor is published as signed, machine-readable SAML metadata through the Jisc UK Access Management Federation MDQ service and onward into eduGAIN, and is also served directly by the institution from shibserv2.abdn.ac.uk. Retrieved live on 2026-09-01 — 200, 14194 bytes of application/samlmetadata+xml from the federation, 200 and 15707 bytes of application/xml from Aberdeen's own host. Advertises SAML 2.0, SAML 1.1 and the native Shibboleth authn profile over HTTP-Redirect, HTTP-POST and HTTP-POST-SimpleSign, plus an AttributeAuthorityDescriptor. This is the only surface in this repository that is unambiguously the institution's own engineering, and it is the class the June 2026 profile of this repo missed entirely. It is not a public developer API: an application cannot obtain an assertion without being registered as a service provider in the federation.

  "University of Aberdeen", OrganizationDisplayName "University of Aberdeen" and shibmd:Scope "abdn.ac.uk",
  with technical contact mailto:webmaster@abdn.ac.uk. The SSO endpoints it advertises are all on shibserv2.abdn.ac.uk
  (5.101.151.154), which serves the same descriptor itself.

x-probe:
  baseURL_status: 200
  self_published_metadata_status: 200
  sso_endpoint_bare_get_status: 400
  note: baseURL is the federation MDQ location because that is the machine-readable artifact an agent
    can actually retrieve. MDQ is served over HTTP only; https://mdq.ukfederation.org.uk does not answer.
    The SSO endpoint returns 400 to a bare GET because it requires a SAMLRequest — that is protocol behaviour,
    not an outage, and it is recorded in x-sso-endpoint rather than as a pointer. shibserv.abdn.ac.uk
    (the entityID host) does not resolve publicly; entityIDs are names, not addresses.
