Grafana LDAP Login Issues

I’m using the Ubuntu Grafana package (6.6.0, which seems to be latest) with LDAP authentication.

After the last update, I’m seeing intermittent login problems.

The primary problem is sometimes it will just…not log you in. It will just continuously redirect you to the login page, even though the login was successful. It will also redirect you to login if you attempt to go to a dashboard directly - basically, acting as if it hasn’t logged you in, even though it should have.

After awhile (anywhere from 5 minutes to an hour), it will just magically start working again with no changes.

Some logs from a time where this happened (debug on - there are no errors of any kind):

Anyone got any ideas as to what could be causing this? Or debugging steps I could try?
