Subject: (PR) 15-day Public Review for SAML V2.0 Kerberos Web Browser SSO Profile Version 1.0
The OASIS Security Services (SAML) TC  members have produced an updated Committee Specification Draft (CSD) and submitted this specification for 15-day public review:
SAML V2.0 Kerberos Web Browser SSO Profile Version 1.0
Committee Specification Draft 02 / Public Review Draft 02
29 November 2011
The SAML V2.0 Kerberos Web Browser SSO Profile allows for transport of assertions using the Kerberos subject confirmation method by standard HTTP user agents with no modification of client software and maximum compatibility with existing deployments. The flow is similar to standard Web Browser SSO, but a Kerberos AP-REQ message is presented by the user agent via the HTTP Negotiate authentication scheme and the Kerberos GSS-API mechanism. The presentation of a valid Kerberos AP-REQ message whose client principal name matches the principal name given in the subject confirmation strengthens the assurance of the resulting authentication context and protects against credential theft.
Public Review Period:
The public review starts 5 December 2011 and ends 20 December 2011. The specification was previously submitted for a 60-day public review . This 15-day review is limited in scope to changes made from the previous review. Changes are highlighted in the diff-marked PDF file included with the specification.
This is an open invitation to comment. OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work.
