I have jamf working on this too, but wondering if y'all have run across this.
We just setup our JDS environment on 9.21 / 10.9 Servers and more or less everything has replicated. However, When I go into C.Imaging and override defaults to point to the JDS, C.Imaging errors out on mounting the JDS, adn the only error I can find is "there was a problem connecting to the server jds.server.com. Check the sever name or IP and try again.
I can ping it, I can do a cmd+k and map it (or at least get to the point where it prompts for credentials).
