In commit d43dc68, @Mic92 split the rootpw option to allow specifying it in a file kept outside the Nix store, as an alternative to specifying the password directly in the config. Prior to that, rootpw's type was `str`, but in order to allow both alternatives, it had to become `nullOr str` with a default of `null`. So I can see why this assertion, that either rootpw or rootpwFile are specified, makes sense to add here. However, these options aren't used if the configDir option is set, so as written this assertion breaks valid configurations, including the configuration used by nixos/tests/ldap.nix. So this patch fixes the assertion so that it doesn't fire if configDir is set.

There was a problem hiding this comment.
Can be written as cfg.configDir == null -> cfg.rootpwFile != null || cfg.rootpw != null for more clarity, but that's completely not important.

Thanks for reviewing! I think that was how I wrote it originally and I found it more confusing that way. Maybe it's just confusing no matter how it's written. 😓

BTW what was the test that you mentioned failed before this PR? |
|
The LDAP tests failed during nix-instantiate when I ran: nix-build nixos/release.nix -A tests.ldap.x86_64-linuxThe configuration there trips the assertion as it's currently written. |

Motivation for this change
In commit d43dc68, @Mic92 split the rootpw option to allow specifying it in a file kept outside the Nix store, as an alternative to specifying the password directly in the config.
Prior to that, rootpw's type was
str, but in order to allow both alternatives, it had to becomenullOr strwith a default ofnull. So I can see why this assertion, that either rootpw or rootpwFile are specified, makes sense to add here.However, these options aren't used if the configDir option is set, so as written this assertion breaks valid configurations, including the configuration used by nixos/tests/ldap.nix.
So this patch fixes the assertion so that it doesn't fire if configDir is set.
