Issue

I see that RHEL6 has RequiredAuthentications2 (and RequiredAuthentications1) documented in the man page for sshd_config. However, this feature doesn't appear to be documented in RHEL7's sshd_config man page.
A few questions:

1) Is RequiredAuthentications2 supported in RHEL7?
2) If so, should this be documented in the sshd_config man page?
