Recently I`ve installed open solaris in my desktop PC.But I could not login as root user through Login screen.
I`ve removed type=role entry in /etc/user_attr file
After removed the the entry the line will be like this
root::::auths=solaris.*,solaris.grant;profiles=All;lock_after_retries=no;min_label=admin_low;clearance=admin_high
and then reboot the system. You can login as root again.
