seems that this got broken when the config option was made to use enums. "secure" got replaced with "enum", which isn't a valid option for the failure mode.
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
This module adds the security.duosec attributes, which you can use to
enable simple two-factor authentication for NixOS logins.
The module currently provides PAM and SSH support, although the PAM unix
system configuration isn't automatically dealt with (although the
configuration is automatically built).
Enabling it is as easy as saying:
security.duosec.ssh.enable = true;
security.duosec.ikey = "XXXXXXXX...";
security.duosec.skey = "XXXXXXXX...";
security.duosec.host = "api-XXXXXXX.duosecurity.com";
security.duosec.group = "duosec";
which will enforce two-factor authentication for SSH logins for users in
the 'duosec' group.
This requires uid/gid support in the environment.etc module.
