Abstract
A received security token includes first access control attributes and a signature of a first identity provider of a first security domain. Additional access control attributes provided by a second identity provider of a second security domain are added into the received security token. The received security token with the added additional access control attributes is re-signed, with a private key associated with a certificate of a second service provider in the second security domain. The re-signing is an assertion in the second security domain that the added additional access control attributes have been provided by the second identity provider of the second security domain. The re-signed received security token is issued for consuming, using the added additional access control attributes, by any service provider in the second security domain.
