Module can't unjoin from domain

[apenadiazApk]

Description

The module works fine to join an RDS instance into Self Active Directory but if for any reason we need to do unjoin to turning back again as stand-alone rds sql server missing parameters to send to api

• ✋ I have searched the open/closed issues and my issue is not listed.

⚠️ Note

Before you submit an issue, please perform the following first:

1. Remove the local .terraform directory (! ONLY if state is stored remotely, which hopefully you are following that best practice!): rm -rf .terraform/
2. Re-initialize the project root to pull down modules: terraform init
3. Re-attempt your terraform plan or apply and check if the issue still persists

Versions

• Module version [6.10.0]:

• Terraform version:
  1.5.2

• Provider version(s):
  1.5.2

Reproduction Code [Required]

...
domain_auth_secret_arn = "arn....."
domain_dns_ips = "dns.ip.dc.1, dns.ip.dc2"
domain_fqdn = "corp.local"
domain_ou = "OU=RDSSQLServer,DC=corp,DC=local"
....

Steps to reproduce the behavior:

No workspaces

No local cache

add the 4 parameters to do the join into self ad
remove it same parameters to do unjoin

Expected behavior

Unjoin from AD

Actual behavior

for example when you join you can see in the plan the 4 parameters above and the process complete.
when you do unjoin from the domain, only see 3, missing domain_fqdn to complete the combination to remove it
in case to reverse and unjoin get an error message

Terminal Output Screenshot(s)

api error InvalidParameterCombination: Ensure all of the self-managed Active Directory parameters have been passed in.
