Environment variable based authentication not working

[akhomyakov]

Hi folks, For some odd reason I can't get auth to work using environment variables on a linux box. This "linux box" part is important as this works just fine on my Mac.

I removed the actual variable values for the purposes of bug report, but they do contain a valid username and password.

Hi @akhomyakov, I just double-checked, and env variables are working fine for me on linux. This is implemented via pretty basic functionality so its hard to imagine what could go wrong here.. https://github.com/vmware/terraform-provider-nsxt/blob/6b49e6799892687bc04d1c31d4b05c03e95ea8da/vendor/github.com/hashicorp/terraform-plugin-sdk/v2/helper/schema/schema.go#L272

I'm curious whether it would work if you provided those variables via terraform variables (via command line) that would be populated by same environment variables?

[akhomyakov]

Hi I didn't forget about this. It just went onto the back burner. The reason I ended up doing this on a linux box is no more, so investing time into investigating this problem is no longer a work priority for me and I must find personal time to do a few tests. I'll post the update when I get to actually test out providing credentials as terraform variables rather than shell environment variables. -Andrey
