All,
I have a multi-server Zimbra install (a cluster I guess). When I deployed, I generated a 1024 CSR and had it signed by GoDaddy. This cert will expire in 5/2010, and when I go to renew it, GoDaddy tells me that it needs to be at least 2048 bits.
The reasonng makes sense, but zmcertmgr won't let me generate a new CSR, or I suppose I should say I can't figure out how to regenerate the CSR.
Any hints?

This particular cluster is running: Release 6.0.5_GA_2213.UBUNTU8 UBUNTU8 FOSS edition.
