auth-source source password lookup for ssh + sudo

[Kai Tetzlaff]

Hi Michael,

with auth-source enabled when SSHing to a server with sudo as 2nd hop
like `notroot@host.example.com|sudo:/etc/passwd` TRAMP apparently tries
to look up the sudo password using `user=root, host=host.example.com,
port=sudo` (at least that is what auth-source-pass tells me with
debugging enabled [1]). Now, why does the lookup use `user=root` instead of
`user=notroot`. Is there a way to change that?

The reason I'm stumbled upon this is that I have multiple accounts on
some hosts and with the current lookup scheme it is not possible to
store sudo passwords for more than one account per host.

Thanks,
Kai


[1] The actual debug output is:

auth-source-pass: searching for entries matching hostname="host.example.com", 
user=#("root" 0 4 (tramp-default t)), port="sudo"
