Allow custom External Login sources
We need the ability to push authenticated users back to WA already logged into their account, like with the Facebook and Google+ integration. The oAuth / Single Sign-on implementation does not allow for the external authority.
Is there any way to integrate with a external login?
We support only Facebook and G+ as external authentication providers. Currently there is no way to use other providers. However if you want to implement single sign-on, then WA could be used as authentication provider. See http://gethelp.wildapricot.com/en/articles/200 for more details.
