login.conf manual page: [1]

     The following capabilities are reserved for the purposes indicated and
     may be supported by third-party software.	They are not implemented in
     the base system.
     passwordtime      time		   Used by passwd(1) to set next pass-
					   word expiry date.

The other capabilities (warnpassword, warnexpire, login-retries) do
not relate to lock-outs attempts.  To my knowledge, there are no other
capabilities that are supported by the base in login.conf that will
lock out an account.  This has been discussed prior [2,3].  It is not
available in the base; the administrator has to manually do this.
