I don't know if this should be considered as bug or "just changed behavior".
sshd -T works in FreeBSD 11.4 (OpenSSH_7.5) and prints details about
current configuration but it does not work with the same configuration
file in FreeBSD 12.2 (OpenSSH_7.9).
# sshd -T
'Match Group' in configuration but 'user' not in connection test
specification.
Once I have any "Match" in sshd_config then sshd -T does not work. It
needs additional -C user=fakeuser to print configuration. (I just needed
to view supported ciphers)
You can try it with default sshd_config and add something like this:
Match group sftponly
ChrootDirectory %h
...or just ucomment section "Match User anoncvs".
I think sshd -T should still work without -C as it was in older versions
and print configuration for any non-matched criteria.
