There is a minimum amount of attributes to supply when you connect your IdP to SURFconext. Not supplying the attributes urn:mace:dir:attribute-def:uid and urn:mace:terena.org:attribute-def:schacHomeOrganization will cause a fatal error beceause because those are needed to generate the NameID. Your IdP cannot be connected to SURFconext without these. Not supplying the attributes urn:mace:dir:attribute-def:displayName and urn:mace:dir:attribute-def:mail will cause a warning. A lot of services depend on these. The above mentioned are the bare minimum and will probably result in services not being able to connect to your institution. As a rule of thumb, supply the attributes as depicted on this page or those depicted in the configuration manuals on the page (Dutch) 'Handleidingen en Richtlijnen'.

SURFconext considers the attributes nlEduPersonOrgUnit, nlEduPersonStudyBranch and nlStudielinkNummer deprecated. When you register a new IdP or SP at SURFconext, these attributes will not be allowed for use with SURFconext. Excisting Existing IdP's and SP can use these attributes untill untll further notice.
