Hi Rob
Sorry for the trouble
I am still struggling
my open ssh version is 6.1
sssd version is 1.8
can you please suggest me

# This sshd was compiled with PATH=/usr/local/bin:/usr/bin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.
# If you want to change the port on a SELinux system, you have to tell
# SELinux about this change.
