Consume 3rd party authentication (providers) in SP13

Question

I have a situation where I should have multiple authentications for my SP13 farm.
1. Since Claims is dominant in SP13, how can I integrate different (multiple) authentications? I am not clear on how claims works internally :(
2. How users from different authentication types can be grouped into SharePoint specific groups?

Hi GEM,
1.Claims-based authentication is more general authentication mechanism that allows users to authenticate on external systems that provide asking system with claims about user. For how claims-based authentication works, you can have a look at the blog:
http://www.c-sharpcorner.com/UploadFile/Ashush/authentication-methods-in-sharepoint-2013/
For integrating multiple authentication methods in claims based web application, you can refer to the blog:
http://www.dotnetspark.com/kb/2845-configuring-multiple-authentication-providers.aspx
2.For adding users from diffferent authentication types into SharePoint groups, there is no special steps. Because with claims-based identities, a user obtains a digitally signed security token from a commonly trusted identity provider. The token contains
a set of claims. Each claim represents a specific item of data about a user such as his or her name, group memberships, and role on the network. Claims-based authentication is user authentication that uses claims-based identity technologies and infrastructure.
Applications that support claims-based authentication obtain a security token from a user, rather than credentials, and use the information within the claims to determine access to resources.
