Server Connection and Other Parameters

The AllowGroups, AllowUsers, DenyGroups, and DenyUsers keywords control which users can or cannot use ssh.

The LoginGraceTime, MaxStartups, PermitRootLogin, and PermitEmptyPasswords keywords set controls on users who are logging in. StrictModes causes sshd to check file modes and ownership of the user's files and home directory before login. UseLogin specifies whether login is used for interactive login sessions. Turning this keyword on should not be necessary and is not recommended for the Solaris environment.

Subsystem configures a file transfer daemon for using sftp.
