locking accounts after 3 unsuccessful login attempts

[Mike_Ca Li]

Hi:
How can the above the accomplished? I read that PAM can be configured to do so, but can it be done via a script?
Thanks.

If your system is trusted then you can set the system wide umaxlntr to lock the accounts.

# /usr/lbin/modprdef -m umaxlntr=3

With the above command, user's account will be locked after 3 unsuccessful attempts.

You cannot configure an untrusted system to lock the user accounts after unsuccessful tries.

and NO it cannot be done via script.

By default a trusted system will lock an account after 3 unsuccessful attempts.

If your system is not trusted mode change it to trusted mod.No need to do any modification bye default the max lgin atempt would be set to 3
