This feature is new in the Solaris Express 10/04 release.
The sshd daemon uses the variables in /etc/default/login and the login command. The etc/default/login variables can be overridden by values in the sshd_config file.
For more information, see “Solaris Secure Shell and Login Environment
Variables” in the System Administration Guide: Security Services. See also the sshd_config(4) man page.
