Hi,

I didn't find any topic that would give me a definitive answer. Also, I'm not that good at how certifications work at this level.  
I was thinking about creating a new set of certificates for my Elastic cluster and I'm not sure if adding CRL distribution points ([man](https://www.openssl.org/docs/manmaster/man5/x509v3_config.html)) would be respected by Elastic products (mainly ES, but I also have MB, FB, LS, APM servers).  
If I create the certificates correctly, will the process check if the given certificate was revoked?  
If so, is there anything I need to be aware of?

Thank you!

No, Elasticsearch does not support CRLs.
