→Persistent user identifiers
=== Persistent user identifiers ===
For some most services, it is necessary to store application-specific data, such as user edits for a wiki page. This data is stored in some a database local to the SP, while the key between the user and the database entry is a the '''persistent user identifier'''.
Persistent identifiers can be:
* '''persistence''': IdPs must ensure that the identifier does not change during the life-cycle of the user at the institution.
* '''non-reassignable''': IdPs must ensure that an identifier of a user will not be reassigned to another user.
* '''opacity''': opaque identifiers are do not refer to any personal data
* '''targeted''': targeted identifiers are different for each SP, thus the SPs are unable to build common user profile without the cooperation of the IdP. Such identifiers are preferred from privacy reasons.
Persistent identifiers can be transferred in SAML attributes or in NameID of a SAML Assertion. Certain SP implementations (such as Shibboleth 2.x) can hide the details of the transfer, and can provide a persistent identifier in REMOTE_USER header.
=== List of attributes ===
In this specification, only mandatory and recommended attributes are specified. The [[HREFAttributeSpec|Hungarian Attribute Specification]] contains descriptions of the optional attributes as well. If you have any questions regarding the optional attributes, please contact the Federation Operator.
