[Trellis-developers] Single Sign-on

[Shaddy]

Single sign-on is a feature requested by many corporate clients and 
because of the vast difference in behavior of logging in with single 
sign-on, its not something that can be nicely supported side-by-side 
with conventional sign-on. The solution is a single sign-on plugin.

There exists a standard called SAML (Security Assertion Markup Language) 
designed for single-sign on. We shall design this plugin to be compliant 
with this standard. More information can be found on Wikipedia:
