we have a local TFS 2015 environment and a S3 compatible storage where we want to store large files to. 

I found this: <https://github.com/meltingice/git-lfs-s3>

Is it possible to use it with a S3 compatible storage instead of an Amazon S3? I tried it but got stuck with the authentication and configuraton as I can't see where to specify the S3 compatible endpoint. I neither can see where the Amazon S3 endpoint is specified so I think thats hidden in the used AWS Helper libs used in this project. 

So I think my scenarion is not possible, right? 

Any other Ideas how to use git with S3 compatible storage? Do we have to write our own lfs api? 

thanks.
