This one is definitely going to bite a few people, especially those that have got used to pfexec on OpenSolaris.
If you've used OpenSolaris, you'll notice this differs from OpenSolaris at steps 6 and 7. However, this change has revealed one teeny weeny issue:
Gksu Does Not Report Expired Password (6995127). (Requires My Oracle Support access)
This IS documented in the Solaris 11 Express release notes, but I can guarantee this will be missed by most people and the first they'll know of it is when they're prompted by a GUI app to enter the root password and it fails saying the password is wrong. The release notes also don't detail the workaround. For that you need to view the CR referenced.
Until such time as this issue is resolved, you need to login as the user created during installation, fire up a terminal and run "
su". You'll be prompted for the old root password (your current user login password) and then asked to set a new password for root.
Before you get all excited about
sudo(1m) now being included in Solaris, take note of the following excerpt from it's man page:
sudo does not create audit(2) records; for a Role Based administration solution that performs auditing of all actions, please refer to rbac(5).
So if auditing is important, use RBAC and not sudo. If you're used to doing everything using pfexec, you can currently still add the "Primary Administrator" profile to your username in
/etc/user_attr, but apparently this is due to change in a later release when this profile is EOLd.
