Steps to Reproduce:

1. Leave the 'Cluster Name' field blank when creating a new cluster

Results:
Error 'User XXX cannot create node pools...'

@gravityforall - Ryan, this is a bad error message. This is because you don't have Cluster Name. Which is a required field.

I can reproduce this issue in master 05/14

1. create a Standard User user1
2. login as this user user1
3. create a RKE cluster with DO node driver
4. Input cluster name and select other fields
5. Click create. The request for creating nodepool gets 403 with the similar error message.

I think this is a backend issue. It looks like we can do nothing from UI side.

@prachidamle i thought we made the cluster name required in #13075

[prachidamle]

@deniseschannon @loganhz yes, clusterName is now a required field and has to be unique as well

[loganhz]

@deniseschannon @prachidamle Standard user still can not create cluster with master 06/10.
It's not a cluster name issue. Maybe we should rename the issue.

clusterregistrationtokens.management.cattle.io is forbidden: User "u-c9qrf" cannot create clusterregistrationtokens.management.cattle.io in the namespace "c-98wgj"

[loganhz]

If standard users create a custom or import cluster
POST https://localhost/v3/clusterregistrationtoken returns 403.

If standard users create a cluster with node driver

POST https://localhost/v3/nodepool returns 403

Duplicated with #12532

[prachidamle]

The error message has been fixed to indicate that clusterName is a required field, as seen below:
