# Sample script to generate a certificate request which can be sent

# globus-ssl.conf file.
#
# When generating a certificate request and private key for a 
# globus gatekeeper daemon, use the -nopw option, so the
# key is not protected by pass phrase.

  Example Usage:

    Creating a user certifcate:
      grid-cert-request

    Creating a host or gatekeeper certifcate:
      grid-cert-request -host [my.host.fqdn]

    Creating a LDAP server certificate:
      grid-cert-request -service ldap -host [my.host.fqdn]

  Options:

    -?, -h, -help,     : Display usage
    -usage 
    -cn <name>,        : Common name of the user
    -commonname <name>
    -service <service> : Create certificate for a service. Requires
                         the -host option and implies that the generated 
                         key will not be password protected (ie implies -nopw).
    -host <FQDN>       : Create certificate for a host named <FQDN>

                         certificates are placed in $HOME/.globus, host 
                         certificates are placed in /etc/grid-security and
