Vault - Assigning multiple aliases to one identity group

As the title suggests, I’d like to assign the same canonical id to multiple identity group aliases. I’m using Terraform to provision my Vault environment.

I’ve raised a similar question in StackOverflow with my configuration, if you’d like to take a look right here.

Replying to an old post for anyone who finds this thread in the future, but as of today this can’t be done. It’s a vault bug/feature request 24538
