SAML/SSO support

[ghost]

Greetings.
Is this possible to support SAML/SSO?

SSO itself shouldn't be hard to implement (open the URL in an browser, redirect to a local python http server to get the login token?), but first the sign in UI will have to change to allow for more options than normal user/password login:

• Show an interface where the user can either enter a server URL or choose from a list of popular servers, e.g. this one
• Send a request to chosen server to know which login methods it offers
• Show an appropriate interface depending on the method, e.g. the current user/password form or a button to begin the SSO process

I might take a look at this after the next release.

Greetings,
Any progress concerning this issue?

I'm finishing the work on device management and basic E2E verification, then it will be the next big thing I'll be focusing on, unless cross-signing support in matrix-nio is out by then (improbable).

You can now test SSO in the dev branch, it will officially land in the next release. Note that the UI isn't complete, since the server list has yet to be implemented.

Also until matrix-nio/matrix-nio#194 gets merged, you need to install this nio branch.

All done in 0.6.1.
