I'm not an expert Freebsd administration, so any comments and suggestions are welcome. login.conf manual page: [1] RESERVED CAPABILITIES 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.
