ok, either you aren't forwarding your private key properly, or it's not located on tools-login in ~/.ssh

Yup, that's it. I wasn't forwarding it correctly.
No, the problem lies with Tools in that host-based authentification between tools-dev and tools-login isn't working anymore. ssh'ing from tools-dev and tools-login to tools-exec-01 succeeds.
I discovered that both tools-dev and tools-login had the ssh_hba variable unset, but setting it back to "yes" didn't fix the issue. There were some changes to the submit host mechanism in conjunction with the introduction of the webnode role, but I don't see anything obvious. Need to debug further.
