Hello everyone,
If you don't edit/create dashboards on grafana.wikimedia.org feel free to skip the rest of this email, it does not affect you. Those of you who do, please read on.
Our grafana installation dates back quite a bit and it has a custom LDAP authentication and authorization implementation. Nowadays Grafana has native support for LDAP and can query LDAP groups. After some lengthy evaluation and problem solving in https://phabricator.wikimedia.org/T170150, the SRE team feels ready to deprecate the custom LDAP implementation and migrate to the native one. What does this mean?
* grafana-admin.wikimedia.org (the entry point for users to authenticate and create dashboards) will be removed * grafana.wikimedia.org WILL remain as is and will very only slightly change, specifically the login menu part (see below) * You will be logging in using a menu in the left hand side of grafana.wikimedia.org using the exact same credentials as before. * The grafana database user attributes email and name will be automatically populated on login from LDAP and enforced. This is expected to be irrelevant for almost everyone, but if you 've edited manually your profile in grafana expect those 2 fields to be overriden with data from LDAP.
The date for the migration is June 27th 09:00 UTC and the maintenance window will be 3 hours long. We don't expect it to really last that long however. Expect grafana.wikimedia.org downtime during that timeframe
Regards,
