Is it really a different host and why? I think we'd need to see the full 
output to know what's going on.

A given host can only get certificates for itself or those delegated to 
it. Hostnames are used for this enforcement so if they don't line up 
you'll see this type of rejection.

Without more context it's hard to say. 389 is rather chatty about things 
and of course when it starts it has no ticket so it logs a bunch of 
stuff, eventually (hopefully) gets one, and then shuts up.

I wouldn't get too hung up on particular services just yet. Without 
valid certs things will fail and those problems will cascade. I think we 
just need more details at this point.
