Heads up @cluster/ocp5-admin - the "cluster/ocp5" label was applied to this issue.

Fixed
HSSO->coe-ssoadmin->IdentityProviders->RedHatSSO -> Mappers --> addToGroup-global-cluster-reader
Category: Group Importer
Type: HardCoded Group
Group: /global-cluster-reader

Should be applied on next login of a COE-SSO-Admin user to the cluster.
