Looking to see if there’s anyone with some ideas about a problem we’ve got that’s becoming more of an issue.
Setup here is that we’ve got Grafana instances (v4.2.0 at the moment) that are using MySQL as their backend database (instead of the budled SQLite) and that MySQL is a clustered one (NDBCLUSTER table type). User authentication is being done against our LDAP/AD setup
This arrangement seems to work fine with one drawback. On occasion a user will try to log in, but will then be told that they are “unauthorised”. When someone else checks, the user account is still there, but if that account is then deleted, the user can then login as normal. Although we’ve then got a reassign any admin rights, etc.
We can’t see any errors in MySQL, and if there were it’d be a subtle issue for just one row in a table to become corrupted.
Has anyone out there in Grafana-land seen something similar, or should I just go ahead and log an issue?
