[SunHELP] Locked Accounts

[Vikas Gandhi]

Hi All
  I face a peculiar problem. When I am creating new accounts using command
prompts(useradd), I have *LK* in the shadow (given below)
temp5:*LK*:12424::::::

Now when I do 
bash-2.03# passwd temp5 
New Password: 
Permission denied

How can I change my passwd thru passwd command.
FYI: I do not want to manually edit /etc/shadow under any circumstances.

Regards
Vikas
