Setup Artifact binding
In order to use Artifact binding, TElSAMLServiceProvider.SPToIDPBinding property should be set to TSBSAMLBindingType.sbtArtifact. TElSAMLServiceProvider.ArtifactStorage property should be initialized with TElMemoryArtifactStorage instance that is used to store information about created artifacts and can be shared between TElSAMLServiceProvider objects.
