While we would love to support AWS Identity and Access Management Using SAML, true integration of SAML (Security Assertion Markup Language) is outside of the realm of Identity Federation for AWS – that being said, a main value proposition of Identity Federation for AWS is to provide functionality similar to SAML by leveraging the alternative AWS options for Identity Federation – you thereby gain the same benefits of federated access and a unified directory for all Atlassian products via Crowd. 

True SAML support would best be addressed by Atlassian Crowd itself – a related feature request is tracked by Atlassian in , so please add your vote there to increase the priority. Also, don't hesitate to get in touch with us to discuss alternatives.
