Windows clustering cliusr certs

[Trustmeimadoctor]

Hi quite new to clustering and I've noticed that a cert on one of my clusters is expiring it's for the cliusr account I've googled but can't find anything about the cert just the account.

Question is is the cert needed post cluster setup it's only valid for a year and is intended for server authentication and client authentication. It seems there is one per node possibly

Seems I was binging it rather than googling. Seems they should be automatically managed so should renew with an event of 2049
