Re: wrong password attempt

Hi Prakash,
Yes u can restrict user to login after 3 wrong attempt of login and make it unlock also.
Please edit the file /etc/default/security
set the options as you want.
U can also set password length,password expiry, and many more.
To unlock the user,
#/usr/lbin/getprpw username
this is check
#/usr/lbin/modprpw -k username
to unlock the account.

Hope this solves ur query.

You can do it using command line and sam.

command line.

and you can verify using command

/usr/lbin/getprdef -m umaxlntr

through sam.
