Version 2020-04-22
This document specifies recommendations for upstream metadata produced by eduGAIN participants. Failure to comply with these recommendations will result in a warning produced by the eduGAIN metadata validator using the eduGAIN SAML profile v2.
The recommendations are organised as a set of rules which may be easily verified by the eduGAIN metadata validator.
The rules marked red are actually specification errors and should be upgraded to validator errors (to be discussed within the eduGAIN SG)
The significance column is meant for possible future use, i.e. grouping problems in order to solve the most important first. Proposed significance range is from 1 (least significant) to 5 (most significant). If found useful, this classification should be subject to a future discussion in the eduGAIN SG.
| Condition | Level | Significance | Reason | |
|---|---|---|---|---|
| 1 | Signing certificate expired | 1-global | 1 | Currently implemented as a validator warning. To be confirmed by the SG. |
| 2 | md:EmailAddress in md:ContactPerson element should start with mailto: prefix | 2-entity | 4 | This violates line 495 of https://docs.oasis-open.org/security/saml/v2.0/saml-metadata-2.0-os.pdf and should be considered an error! |
| 3 | SIRTFI attribute present and security ContactPerson definition found but attribute value of {http://refeds.org/metadata}contactType not equal http://refeds.org/metadata/contactType/security | 2-entity | 2 | SIRTFI specification error |
| 4 | SIRTFI attribute present but no security ContactPerson definition found | 2-entity | 2 | SIRTFI specification error |
| 5 | shibmd:Scope with no regexp attribute | 2-entity | 5 | https://wiki.shibboleth.net/confluence/display/SC/ShibMetaExt+V1.0 recommendation |
| 6 | mdattr:EntityAttributes placed in md:Extensions element of SPSSODescriptor/IDPSSODescriptor, expected in md:Extensions element of md:EntityDescriptor | 2-entity | 1 | Since http://docs.oasis-open.org/security/saml/Post2.0/sstc-metadata-attr.html does not define appearance of this element in places other then md:Extensions element of EntityDescriptor it is most likely that the condition is a result of a mistake. |
| 7 | mdrpi:RegistrationPolicy not found | 2-entity | 3 | eduGAIN SAML profile Section 3 |
