Hi. I am writing because I am curious about mattermost server license  
I am considering using the matermost open source.  
But I saw the policy that if I modify the mattermost server source, I have to make public the source because of AGPL.

Here’s what I’d like to revise.

- When user sign in, I’m going to add my company’s groupware api to mattermost sign in source.
- And when user sign up, I’m going to authenticate with groupware API.

In this case, **it’s inevitable to modify the mattermost server source.**  
**if so, does the AGPL license apply? Or is a MIT license enough?**
