hi din,

you can use command "passwd -l user_id" to lock user account. for example:
#passwd -l yulianto
#logins -ox |grep yuli
yulianto:1004:sysadmin:14:Yulianto ITDC-sysadmin:/home/yulianto:/usr/bin/ksh:LK:000000:-1:-1:-1
#grep yuli /etc/passwd
yulianto:*:1004:14:Yulianto ITDC-sysadmin:/home/yulianto:/usr/bin/ksh

the field of encrypted password will changed to *

Well there is vipw(1). Or passwd(1):
passwd -r files [-d|-l] [-f] [-n min] [-w warn] [-x max] name

As I said, you either use vipw(1) or passwd(1).
In particular "passwd -d" will unlock it.

Din,

# usermod -x administrative_lock_applied=0 username
# passwd username

can't we unlock a user account without resetting the old password or changing the account to null password? My doubt is, the user should be able to login with their own old password.

Unfortunately not with passwd(1). With vipw(1) you just add a "*" to the start to lock, and remove it to unlock.

Unfortunately it doesn't look like it.
