In my organization we are investigating the possibility of publishing some content to AGOL, but the authentication should be done against our internal Identity Server. At the moment this Identity Server does not exist, but we are planning to use the Thinktecture Identity Server.
Here I have seen a list of supported identity providers: http://doc.arcgis.com/en/arcgis-online/administer/enterprise-logins.htm#ESRI_SECTION1_E666FC046A1746...
Thinktecture is not appearing, so my question is: is it going to be supported anytime soon? Is there any "hack" that I could do to make it work in the meanwhile? Or we should definitely use one of the listed identity providers?
