HOW to set unlimited login attempts for user in Solaris?

Hi Admins,

HOW to set unlimited login attempts for user in Solaris ?

And do I need to insatll any packages before doing this?

Thanks.

You just have to edit(or add) entry in /etc/user_attr. Check this man page: user_attr(4) (man pages section 4: File Formats)
Look at "lock_after_retries".
