Documentation on how to use the accounts.url option in the sftp and ftp frontends

[marlowe]

Hi All

I was looking through the docs in relation to the sftp/ftp frontend and it mentions an option for an accounts url

[sftpd] enabled = true port = tcp:8022:interface=127.0.0.1 host_pubkey_file = private/ssh_host_rsa_key.pub host_privkey_file = private/ssh_host_rsa_key accounts.url = ​https://example.com/login

Is there any further documentation on what is returned or expected from the accounts.url? What is send to the URL and how? I didn't seem to find this in the documentation.

Thanks, Jimmy
