For DBA's or (Unix admins with less experience), when you need to bind your web or app server to a privileged port  (<1024) on Solaris 10 and you cannot be given the root account (who wants it anyway), you need a way to startup your server and bind to this low port. 
I've done this before with RBAC (i.e. exec_attr, prof_attr), but knew there was an easy one line command to provide this privilege to a non-root user.
Here's the simple command.  You must run it as root. 

usermod -K defaultpriv=basic,net_privaddr

Now the user can run applications that need to bind to privileged ports (i.e. port 80).  This adds a line into the /etc/user_attr file:

::::type=normal;defaultpriv=basic,net_privaddr
