+# DNS Provider Configuration
+
+This directory contains the configuration for the DNS provider using FreeIPA.
+
+## Environment Variables
+
+To securely provide the password for the FreeIPA provider, set the following environment variable before running Terraform:
+
+```bash
+export TF_VAR_freeipa_password="your_password_here"
+```
+
+Replace `your_password_here` with the actual password.
+
+Ensure that this environment variable is set in your shell session or in a secure environment management tool before executing Terraform commands.
