I get GRAM Job submission failed because authentication failed: Expected target subject name=”/CN=host/hostname”, Target returned subject name=”/O=Grid/O=Globus/CN=hostname.domain.edu”. Why?
You will get this error when running the client and server, both, on the same machine OR when your Grid is deployed on a local LAN (without access to the Internet or DNS server). This is because the expected target subject name has just the unqualified hostname but the target returned subject name has the fully qualified domain name (e.g. expected is “hostname” but returned is “hostname.domain.edu”). This is usually becuase the client looks up the target host’s IP address in /etc/hosts and only gets the simple hostname back. The solution is to edit the /etc/hosts file so that it returns the fully qualified domain name. To do this find the line in /etc/hosts that has the target host listed and make sure it looks like: xx.xx.xx.xx hostname.domain.edu hostname Where “xx.xx.xx.xx” should be the numeric IP address of the host and hostname.domain.edu should be replaced with the actual hostname in question. The trick is to make sure the full name (hostname.domain.edu) is listed before the nic
