Hi everyone,

I just came across a contradiction between the man page of AuthenticationMethods and the accepted
methods list.

According to the sshd_config manual page:
"""
AuthenticationMethods

Specifies the authentication methods that must be successfully completed for a user to be granted
access. This option must be followed by one or more comma-separated lists of authentication method
names. Successful authentication requires completion of every method in at least one of these lists.
""""

But in reality the also an empty list is accepted by sshd (servconf.c:1605).

What is the reason to accept an empty method list? Does the man page need an update?

Thanks and best regards,
/M
