Recently OpenSSH on macOS Sierra was upgraded to 7.3p1 which means that the Include config directive is available, hurray!
However I'm having problems actually using it.
I have the following ~/.ssh/config:
Host github.com
Hostname github.com
User git
IdentityFile ~/.ssh/keys/github_rsa
Host den
HostName narzt-desktop.local
User camden
GSSAPIAuthentication no
AddressFamily inet
Host walle
User CamdenNarzt
HostName WALLE.local
AddressFamily inet
GSSAPIAuthentication no
Include ~/.ssh/config.d/*
I saw here that there might be some useful debug output if I added a bunch of -v flags to my ssh commands, yet when I test the config for a host in one of the included files I get this:
$ \ssh -vvvvG git-codecommit.us-east-1.amazonaws.com

(Ignore the line numbers in the first bit, I deleted some comments to save space in the question) The user should be the user specified in the ~/.ssh/config.d/metabolistics.conf file, and the identity file should likewise be the one specified in the included config file. I can't post the contents of the ~/.ssh/config.d/metabolistics.conf file, but it's format is exactly the same as the main ~/.ssh/config file but without any further includes.
I checked the permissions and they look fine to me:
$ ls -lhRa ~/.ssh/config*
