The current LDAP servers are old legacy systems slated to be replaced in the very near future. The configuration of these servers and the services that rely on it is non-optimal which results in problems with authentication to some (but not all) services that rely on LDAP.
The new LDAP system is in its final testing phases now and will completely replace the aging infrastructure we have now.
The problem with the system was detected by IT staff with one of our monitoring systems which alerted us. We are not aware of any impact to the community and have received no reports from anyone. If you experienced any authentication problems between 1-2am then please let us know by writing to firstname.lastname@example.org
