git.repo(src="ssh://...") with identity from forwarded SSH agent?

[zimtkeks]

Hi,

I'd like to clone a git repo via SSH (git.repo(src="ssh://...")) on a target host using an identity provided by an SSH-agent on the pyinfra-machine.
The agent itself is working (via ssh_allow_agent=True) and is used by pyinfra to log into the host.
Agent forwarding is also enabled via ssh_forward_agent=True (and I can see it being applied when running pyinfra -vvv --debug ...).

However, cloning the repo fails with error Permission denied (publickey,password).

How can I make this work?

BTW, cloning by running git clone ssh://... manually on the host (with agent forwarding) works as expected.

Thank you very much!
