Actually, I didn't review the patches in this email, I just commented on
the auth-source-pass in the master *right now*, not the patch.  Sorry
for the trouble.

Thanks for clarification.  I have written the same thing in my another
(actual) patch review email, feel free to ignore those parts.

How about communicating with them?

Yeah, you are right, I didn't notice those patches and just commented on
the auth-source-pass in the master *right now*, not the patch.  Please
forgive for the trouble.
