Enabling "CanonicalMatchUser" directive in sshd_config will make sshd to first attempt to obtain canonicalized username from password database before evaluating the Match User block. This is mostly useful for AD and LDAP users where using an alias or just capitalizing some of the letters in a username still authenticates a user but does not match the Match User block.
