SAML library for Golang

 This package contains a partial implementation of the SAML standard in
 golang. SAML is a standard for identity federation, i.e. either allowing
 a third party to authenticate your users or allowing third parties to rely
 on this software to authenticate their users. In SAML parlance an Identity
 Provider (IDP) is a service that knows how to authenticate users.
 A Service Provider (SP) is a service that delegates authentication
 to an IDP. If you are building a service where users log in with someone
 else's credentials, then you are a Service Provider. This package supports
 implementing both service providers and identity providers.
