Work is underway under two approaches.

1.  is the OAuth Support.  It is in the final stages, and should merge 
by H3.
2.  is the U of Kent Federaion blueprint, which is also well underway, 
and will have pieces of it in by H3 as well\\\

The split of Identity from Assignments was essential to a consistant 
approach here.  Henry Nash is taking this to the next with the ability 
to have multiple LDAP IdP, one per domain.

There are three pieces to keep clear.

1.  Mechanism for Identity Attribute delivery.   SQL and LDAP are "pull 
mechanisms"  where as SAML etc are push.  The end result is the same, 
though:  we have some data that we can trust to use as the basis of 
authorization decisions.

2. Mapping.  This is the focus of the current Kent work.  We need a way 
to get the attributes, whatever they are, into a format that Keystone 
understands.

3.  Assignments.  These are owned by Keystone.  This consumes the 
mapping in order to actually give the token the attributes.


In addition, we need rules for registering domains.  Currently, each 
domain is limited to one mechanism.  For example, a domain cannot do 
both LDAP and SQL.   If a given domain will use SAML, it will be limited 
to only SAML.  I suspect that this limitation will be acceptable for the 
near future.  Please let me know if this is not the case.

I was planning on submitting a keystone design summit session proposal on this topic where we could discuss the use cases and requirements that customers are bringing forward and make sure we get all the bases covered.  Sounds like you are seeing interest in this as well.

> As far as I know, the ability to log in to OpenStack via arbitrary Identity Provider (IdP) is a widely desired feature. Therefore, we have decided to integrate Keystone & Horizon with Simple Saml PHP, since it provides a lot of AUTH sources (aka. IdPs), for example LDAP, database, facebook, etc...
