Don´t do this!
That really hurts me. A colleague of me posts two tips how to circumvent two security best practices. Never ever do something like this. I know, you need to login twice when you want to act as root. But being not able to login directly as root has two advantages:
•You don´t start to work as root on regular basis (rm -rf * in a directory is much less problematic when done as a normal user, as root you should search for your installation dvds )
•You can track who got root privileges by your logfiles, as everybody has to login with his own login credentials.
So, dear Solaris newbies: Don´t do this! Never ever! The defaults are made this way with purpose. When you really really need to transport files as root to your server, use scp with public key authentication.
