to do that you’d need some kind of mapping facility. Without modifying sssd I’d suggest
symbolic links.
I thought /bin/shell worked everywhere. It’s /usr/bin that may or may not.

Hrm, is there any provision for different paths for the same shell on different platforms?

Turns out there is a way. It seems to be a recent addition, as it wasn’t in the
documentation I looked at originally.
[nss]
allowed_shells = *
shell_fallback = /bin/bash
The semantics of allowed_shells is kind of interesting.
* any shell in /etc/shells is OK
* any shell is allowed_shells but not in /etc/shells get replaced by the fallback
* if allowed_shells isn’t set, any shell is used, even if it doesn’t exist
So setting allowed_shells to * does what you’d want: any shell in /etc/shells is OK.
Otherwise you getter the fallback.
* as a possible value is relatively new.
This is really what I’d expect default behavior to be if allowed_shells isn’t set.

At the very least, it would be good to restrict it to /etc/shells on the
current machine. Doesn't cover everything, but it's an improvement.
