From the global zone, zlogin into the zone and run "passwd -u root"
I am not able to login via zlogin into the zone
ok, then do it the hard way
and remove *LK* from the root entry
I tried that also & rebooted the zone but its not working. It again comes.
It worked. Actually i forgot to save the file.
I changed the /<zonepath>/root/etc/shadow
Removed *LK* & then from global zone did zlogin -l root zonename
