The Support contact (or contacts) for an entity (identity provider or service provider) registered by a member organisation of the federation is the primary contact for handling user problems. This may identify a helpdesk or a designated support person. This may be the same person as the Technical or Administrative contact. Note however that the Support contact does not have the authority to request changes to the entity: this must be done by the entity's Administrative contact or a Management Liaison for the organisation.
The Support contact may be given as a generic title (e.g. 'Help desk') and generic email address (such as a mailing list).
This contact information is published in the federation metadata, which is in the public domain.
