Reported by: gmejia

The problem was that despite assigning the clusterrolebinding, it failed me due to lack of permissions. I have already found the issue! In the documentation the command for creation of the clusterrolebinding is not complete, it is necessary to indicate the user. The documentation says "oc create clusterrolebinding <role-binding-name> --clusterrole=open-cluster-management:cluster-manager-admin".

I have fixed it with: oc create clusterrolebinding NAME --clusterrole=NAME [--user=username]
