Description

The brand new aws_lakeformation_permissions does not seem to support SAML/AD principals (see console, the CLI accepts them without issues)

on lakeformation.tf line 65, in resource "aws_lakeformation_permissions" "xxx":
65: principal = "${local.saml_provider}:group/xxx"
Error: "principal" doesn't look like a user or role: "arn:aws:iam::yyyy:saml-provider/zzz:group/xxx"

New or Affected Resource(s)

Probably “validateprincipal” should be replaced by something lighter for this field - given the wider possibilities of what a LF principal can be - not only SAML/AD but as well Quicksight.

How about support for IAM federated users? We're using aws_cloudformation_stack resources since aws_lakeformation_permissions doesn't support "arn:aws:iam::account:federated-user/username" principals.

Hi , federated-user ? You mean SAml or AD ? The linked pull request supports all allowed principals , as listed here https://docs.aws.amazon.com/lake-formation/latest/dg/lf-permissions-reference.html
It just needs to be merged ....

In this case, authentication is done via GetFederationToken (FederatedUser), I was able to apply Lake Formation permissions via CLI using the ARN pattern arn:aws:iam::account:federated-user/username. I'm also working with the Lake Formation team to potentially add console support for federated users as to not be forced to use AWS CLI to manage them.

ok, yes, I see. Interesting , never used that.
I will adapt the pull request to include this.
