Name ID Format

Defines the name identifier formats supported by the service provider. Name identifiers are a way for providers to communicate with each other regarding a user. Single sign-on interactions support the following types of identifiers:

• urn:oasis:names:tc:SAML:2.0:nameid-format:persistent

• urn:oasis:names:tc:SAML:2.0:nameid-format:transient

• urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress

• urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified

• urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName

• urn:oasis:names:tc:SAML:1.1:nameid-format:WindowsDomainQualifiedName

• urn:oasis:names:tc:SAML:2.0:nameid-format:kerberos

• urn:oasis:names:tc:SAML:2.0:nameid-format:entity

The Name ID format list is an ordered list, the first Name ID has the highest priority in determining the Name ID format to use. If the user does not specify a Name ID to use when initiating single sign-on, the first one in this list is chosen and supported by the remote Identity Provider.

A persistent identifier is saved to a particular user's data store entry as the value of two attributes. A transient identifier is temporary and no data will be written to the user's persistent data store
