Do you _really_ want _all_ of these turned on?
You should decide on what basis users are permitted to run these
programs, and only turn on the relevant authentication.

Check its permissions. Ssh authenitcation and configuration files
generally need very restricted write permissions (only the owner) and
some of them need restricted read (eg private keys may not be readable
by other than the owner).

Do a test ssh. "tail -F /var/log/secure" on the target server while you
do so. It will report the reason access is refused. Then you will have a
better idea of what to look for.
