Adding a New Grafana User to a Secure Data Fabric Cluster

In a secure Data Fabric cluster, adding a new Grafana user requires an extra step to ensure that the user can be authenticated through the CLDB.

Beginning with EEP 5.0.0, Grafana no longer uses its own database to authenticate on secure Data Fabric clusters. On secure clusters, when you enter your user name and password into the browser, the Grafana server sends the user name and password to the CLDB, and the CLDB authenticates using the Pluggable Authentication Module (PAM) and HTTPS.

Because authentication relies on the CLDB, any new user that you add to Grafana must also exist on the Data Fabric cluster. Therefore, to add a new Grafana user in a secure Data Fabric cluster:

  1. Add the user to the Linux system first. This user must have the same Linux UID and GID on every node in the Data Fabric cluster.
  2. Add the same user to Grafana, making sure that you use the user ID you added to the Linux system. In Grafana: Settings > ServerAdmin > Users > Add new user.
