slapd and LetsEncrypt certificates: does a cert renewal necessitate a server restart?

[Jean-Francois Malouin]

Hi,

As the subject say, I'm contemplating the use of LetsEncrypt TLS certificates.
Is there a way to make slapd aware of a cert renewal (they happen every 90
days) without restarting it, ie, with minimal service interruption?

thanks,
