Hi Andrew, mosh doesn't use pam directly, and instead leverages ssh to do the initial authentication checks (whether it uses PAM or not is up to your system configuration). There's actually a long-standing open issue ( https://github.com/mobile-shell/mosh/issues/529) about improving this, but there's no solution agreed upon or timeline decided.
Depending on what you want to accomplish, a wrapper script around mosh-server might be the expedient way to solve your problem.
