Cannot log in if shell is set to /usr/bin/bash

So I just ran into an interesting issue. On Arch Linux, if I create a user that uses a shell from /usr/bin they cannot log in. I create the user with:
useradd -m -G wheel -s /usr/bin/bash username
and when they try to log in, they get 'Login Incorrect'. But if I edit /etc/passwd and change the shell to /bin/bash, everything works fine.
Any ideas what's going on here? Thanks!

Is there an executable calledbashin/usr/bin? Is this also listed in the list of valid login shells (/etc/shells)?

Also, check the logs. On Debian/Ubuntu, the authentication stuff goes to/var/log/auth.logand any messages from PAM modules should be there, too. On Arch, they might be somewhere else, or perhaps you'll just have to go throughjournalctl: unix.stackexchange.com/questions/114189/where-are-my-sshd-logs

As the Arch Wiki makes clear:
Warning: In order to be able to log in, the login shell must be one of
those listed in /etc/shells, otherwise the PAM module pam_shell will
deny the login request. In particular, do not use the /usr/bin/bash
path instead of /bin/bash, unless it is properly configured in
/etc/shells.
cat /etc/shells

If bash is in /bin/bash and /bin and /usr/bin are not linked together, then the login program cannot start the shell if you specify a wrong path to Bash.
If the binares are linked together, then you need to edit /etc/shells to include both variants.
