Creates the group without error. Next, add a tag to trigger an update.

resource "oci_identity_domains_group" "the_group" {

  #Required
  display_name  = "test-new-group"
  idcs_endpoint = var.domain_endpoint
  schemas = [

Debug Output

Notice the issue as shown in debug output

Group.urn:ietf:params:scim:schemas:oracle:idcs:extension:group:Group:owners references a User with ID d459ecb1230d413596c786a043f58eb4 that does not exist
2024-06-04T13:50:45.724-0400 [DEBUG] provider.terraform-provider-oci_v5.44.0: {"schemas":["urn:ietf:params:scim:api:messages:2.0:Error","urn:ietf:params:scim:api:oracle:idcs:extension:messages:Error"],"detail":"Group.urn:ietf:params:scim:schemas:oracle:idcs:extension:group:Group:owners references a User with ID d459ecb1230d413596c786a043f58eb4 that does not exist.","status":"400","urn:ietf:params:scim:api:oracle:idcs:extension:messages:Error":{"messageId":"error.common.validation.invalidReferenceResource","additionalData":{"invalidReferenceResourceId":"d459ecb1230d413596c786a043f58eb4"}}}
The error is only partially correct. Here is what the owners attribute has as was set when the group was created:
"owners": [
{
"$ref":"https://idcs-0fb561ef6dd083fb55b4150d4973b309.identity.oraclecloud.com:443/admin/v1/Users/d459ecb1230d413596c786a043f58eb4",
"display":"",
"type":"User",
"value":"d459ecb1230d413596c786a043f58eb4"}
]
What is true is that user d459ecb1230d413596c786a043f58eb4 is not valid in domain with endpoint https://idcs-0fb561ef6dd083fb55b4150d4973b309.identity.oraclecloud.com:443 which is the domain of the group being created. However, what is failing here is that the owners field is assuming that the user creating the new group is part of the same domain which is not true.

Here my SDK credentials are from a different domain but with privileges to manage the entire tenancy including the domain that is the target of this new group. When I created the group using SDK credentials from DomainA and attribute_sets = ["all"] the owners value (and for that matter idcs_created_by and idcs_last_modified_by) both created user $ref values that attached my actual user ID (from my Domain) to the Domain endpoint of the target Domain and called that a valid reference to the owner and creator. That is incorrect as there is not requirement for the creator of a group to be a member of the Domain—only that the creator of the group be a user with privileges to create groups in the domain.

Panic Output

Expected Behavior

Actual Behavior

Steps to Reproduce

terraform apply for a new identity_domains_group resource with attribute_sets = ["all"]. Ensure credentials of the user running apply are from a domain other than where the new group is being created.
Update the group to trigger a change event (i.e. add new Freeform Tag) then apply
Note the error that complains in debug output that (SDK) user is invalid because it assumes the SDK user is in the same domain that is being modified.
