Requirements for SAML2 Service Providers v20160916 (Draft)
The following describes the technical and administrative checks that will be made before a service provider is admitted into the SAFIRE federation within the SAML2 Technology Profile. It also serves as a checklist for service provider operators for assessing their readiness to participate.
Metadata
- MUST1 have an entityID that is a URL (well-known location). The URL SHOULD use the https scheme and it is RECOMMENDED that valid metadata be available at this URL.
- MUST use secure (https) end-points for any
<md:AssertionConsumerService>or<md:SingleLogoutService>. - MUST contain an
<md:Organization>element, where:<md:OrganizationName>MUST reflect the legal name of the juristic person.<md:OrganizationDisplayName>MAY reflect a commonly known or shortened version of the organisation’s name<md:OrganizationURL>SHOULD contain the organisation’s web site address.
- MUST contain at least one
<md:ContactPerson>ofcontactType="technical"and SHOULD contain one ofcontactType="support". Where<md:EmailAddress>is given this SHOULD be a role account rather than an individual. - MUST contain an
<mdui:UIInfo>, with at least the following elements set:<mdui:DisplayName>— meaningful name for service.<mdui:Description>— short (max 140 chars) explanation of the purpose of the service, such that it is reasonably obvious why the attributes requested are required.<mdui:PrivacyStatementURL>— web site containing a copy of the service provider’s privacy policy.
- It is RECOMMENDED that a
<mdui:Logo>be provided. Any logo MUST be served from a secure (https) server. Logos SHOULD have an aspect ratio as close to 1:1 as possible and SHOULD be at least 100x100 pixels (although 300x300 is RECOMMENDED). - SHOULD NOT contain a
<mdrpi:RegistrationInfo>element (any existing one SHALL be removed by the federation agregator) - MUST contain
<md:RequestedAttribute>entries. - SAML certificates included in metadata SHOULD be self-signed.
- web server certificates used for end-points MUST use PKI that is reasonably likely to be embedded in the browser of all users of the service. Unless an explanation is provided, these SHALL be tested against the root CA lists of common browsers.
Language and Localisation
The SAML metadata specification allows display elements such as <md:OrganizationName> to be localised by using the xml:lang attribute to specify a BCP 47 language code. In common with other federations worldwide, English (xml:lang="en") MUST always be included and will be used as the default when no localised version is available.
