In the haproxy log, I can see the connection was made. The ldap servers in the
backed are definitely responding properly (I can connect to them directly, and
numerous applications are using this haproxy as ldap source, and it works
perfectly fine).
I suspect it is _something_ in M17.
When I downgraded to 2.0.0.v20210213-M16, it works fine - I can connect as
expected. I have tried M17 with java-16-jdk and java-11-openjdk, no change.
{{Is there anything I could investigate more and help discovering what the
issue might be?}}
