OASIS announced that the Security Services (SAML) Technical Committee has released five approved Committee Draft specifications for public review. These specifications are followon deliverables to SAML version 2.0.

1. "SAMLv2.0 HTTP POST 'SimpleSign' Binding" provides an addition to the bindings described in "Bindings for the OASIS Security Assertion Markup Language (SAML) V2.0." It defines a SAML HTTP protocol binding, specifically using the HTTP POST method, and not using XML Digital Signature for SAML message data origination authentication. Rather, assign the BLOB' technique is employed wherein a conveyed SAML message is treated as a simple octet string if it is signed. Conveyed SAML assertions may be individually signed using XMLdsig. Security is optional in this binding.
2. "Identity Provider Discovery Service Protocol and Profile" is an alternative to the SAML V2.0 Identity Provider Discovery profile in the "Profiles for the OASIS Security Assertion Markup Language (SAML) V2.0" specification. It defines a generic browser-based protocol by which a centralized discovery service implemented independently of a given service provider can provide a requesting service provider with the unique identifier of an identity provider that can authenticate a principal.
3. "SAML V2.0 Attribute Sharing Profile for X.509 Authentication-Based Systems" is an alternative to "SAML V2.0 Deployment Profiles for X.509 Subjects." This deployment profile specifies the use of SAML V2.0 attribute queries and assertions to support distributed authorization in support of X.509-based authentication.
4. "SAML V2.0 Deployment Profiles for X.509 Subjects" is an alternative to " SAML V2.0 Attribute Sharing Profile for X.509 Authentication-Based Systems." This related set of SAML V2.0 deployment profiles specifies how a principal who has been issued an X.509 identity certificate is represented as a SAML Subject, how an assertion regarding such a principal is produced and consumed, and finally how two entities exchange attributes about such a principal.
5. "SAML V2.0 X.500/LDAP Attribute Profile" supersedes the X.500/LDAP Attribute Profile in the original OASIS Standard "Profiles for the OASIS Security Assertion Markup Language (SAML) V2.0." The original profile results in well-formed but schema-invalid XML and cannot be corrected without a normative change.
