NAME

       grid-default-ca - Select default CA for certificate requests

SYNOPSIS

       grid-default-ca [-help] [-h] [-usage] [-u] [-version] [-versions]

       grid-default-ca -list [-dir CA-DIRECTORY]

       grid-default-ca [-ca CA-HASH] [-dir CA-DIRECTORY]

DESCRIPTION

       The grid-default-ca program sets the default certificate authority to use when the grid-cert-request script is run. The CA's certificate,
       configuration, and signing policy must be installed in the trusted certificate directory to be able to request certificates from that CA.
       Note that some CAs have different policies and use other tools to handle certificate requests. Please consult your CA's support staff if
       you unsure. The grid-default-ca is designed to work with CAs implemented using the globus_simple_ca package.

       By default, the grid-default-ca program displays a list of installed CA certificates and the prompts the user for which one to set as the
       default. If invoked with the -list command-line option, grid-default-ca will print the list and not prompt nor set the default CA. If
       invoked with the -ca option, it will not list or prompt, but set the default CA to the one with the hash that matches the CA-HASH argument
       to that option. If grid-default-ca is used to set the default CA, the caller of this program must have write permissions to the trusted
       certificate directory.

       The grid-default-ca program sets the CA in the one of the grid security directories. It looks in the directory named by the
       GRID_SECURITY_DIR environment, the X509_CERT_DIR, /etc/grid-security, and $GLOBUS_LOCATION/share/certificates.

       The full set of command-line options to grid-default-ca are:

       -help, -h, -usage, -u
	   Display the command-line options to grid-default-ca and exit.

       -version, -versions
	   Display the version number of the grid-default-ca command. The second form includes more details.

       -dir CA-DIRECTORY
	   Use the trusted certificate directory named by CA-DIRECTORY instead of the default.

       -list
	   Instead of changing the default CA, print out a list of all available CA certificates in the trusted certificate directory

       -ca CA-HASH
	   Set the default CA without displaying the list of choices or prompting. The CA file named by CA-HASH must exist.

EXAMPLES

       List the contents of the trusted certificate directory that contain the string Example:

	   % grid-default-ca | grep Example
	   15) cd1186ff -  /DC=org/DC=Example/DC=Grid/CN=Example CA

       Choose that CA as the default:

	   % grid-default-ca -ca cd1186ff

	   setting the default CA to: /DC=org/DC=Example/DC=Grid/CN=Example CA

	   linking /etc/grid-security/certificates/grid-security.conf.cd1186ff to
		   /etc/grid-security/certificates/grid-security.conf

	   linking /etc/grid-security/certificates/grid-host-ssl.conf.cd1186ff	to
		   /etc/grid-security/certificates/grid-host-ssl.conf

	   linking /etc/grid-security/certificates/grid-user-ssl.conf.cd1186ff	to
		   /etc/grid-security/certificates/grid-user-ssl.conf

	   ...done.

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of grid-default-ca:

       GRID_SECURITY_DIRECTORY
	   Path to the default trusted certificate directory.

       X509_CERT_DIR
	   Path to the default trusted certificate directory.

       GLOBUS_LOCATION
	   Path to the Globus Toolkit installation directory.

BUGS

       The grid-default-ca program displays CAs from all of the directories in its search list; however, grid-cert-request only uses the first
       which contains a grid security configuration.

       The grid-default-ca program may display the same CA multiple times if it is located in multiple directories in its search path. However, it
       does not provide any information about which one would actually be used by the grid-cert-request command.
