and provider registry.terraform.io/hashicorp/dns v3.2.3

Terraform Configuration

provider "dns"{
    update {
      server = "172.254.10.57"
      gssapi {
      realm    = "TESTSERVER.COM"
      username = var.username
      password  = var.password
      }
    } 
}

resource "dns_a_record_set" "dolapo" {
  zone = "testserver.com."
  name = "interswitch"
  addresses = [
    "192.168.0.1"
  ]
  ttl = 300

An A record should have been created on the dns server configured in the provider block

@RahmanBadru did you get this working? Where did you put your krb5.conf file on windows? Did you have to install any kerb packages? I am actually getting the Error negotiating GSS context: configuration file could not be opened: open : no such file or directory, so wondering / assuming my setup is still off somewhere?

I run into the same error message.

What I think is weird is failed sending AS_REQ to KDC, because in Wireshark I cant even see it trying to send AS_REQ to any server. If I do this with kinit from my macOS or Ubuntu 22 it works fine and I can see the requests on the network. Even tho the terraform provider has everything it requires (keytab, realm infos, krb5.conf) it seems not even trying to send out the request. I have no idea where this get stuck and why it's not getting processed.
