UPDATE
[2019-02-19 13:02:40 | Rob McNicholas]
Sympa stopped accepting logins due to this morning’s changes to our LDAP servers. This problem has been worked around for now. We will have to schedule a maintenance window in the future to upgrade Sympa and fully resolve this issue. That maintenance will be announced separately.
