(

char **

cert_dir

)

Get the Trusted Certificate Directory containing the trusted Certificate Authority certificates.

This directory is determined in the order shown below. Failure in one method results in attempting the next.

1. X509_CERT_DIR environment variable - if this is set, the trusted certificates will be searched for in that directory. This variable allows the end user to specify the location of trusted certificates.
2. $HOME/.globus/certificates - If this directory exists, and the previous methods of determining the trusted certs directory failed, this directory will be used.
3. /etc/grid-security/certificates - This location is intended to be independent of the globus installation ($GLOBUS_LOCATION), and is generally only writeable by the host system administrator.
4. $GLOBUS_LOCATION/share/certificates

Parameters:

cert_dir

The trusted certificates directory

Returns:

GLOBUS_SUCCESS if no error occurred, and a sufficient trusted certificates directory was found. Otherwise, an error object identifier returned.

globus_result_t globus_gsi_sysconfig_get_user_cert_filename_unix	(	char **	user_cert,
		char **	user_key
	)

Get the User Certificate Filename based on the current user's environment.

The following locations are searched for cert and key files in order:

1. environment variables X509_USER_CERT and X509_USER_KEY
2. $HOME/.globus/usercert.pem and $HOME/.globus/userkey.pem
3. $HOME/.globus/usercred.p12 - this is a PKCS12 credential

Parameters:

user_cert	pointer the filename of the user certificate
user_key	pointer to the filename of the user key

Returns:

GLOBUS_SUCCESS if the cert and key files were found in one of the possible locations, otherwise an error object identifier is returned

globus_result_t globus_gsi_sysconfig_get_host_cert_filename_unix	(	char **	host_cert,
		char **	host_key
	)

Get the Host Certificate and Key Filenames based on the current user's environment.

The host cert and key are searched for in the following locations (in order):

1. X509_USER_CERT and X509_USER_KEY environment variables
2. registry keys x509_user_cert and x509_user_key in software\Globus\GSI
3. \<GLOBUS_LOCATION\>\etc\host[cert|key].pem
4. \<users home directory\>\.globus\host[cert|key].pem

Parameters:

host_cert	pointer to the host certificate filename
host_key	pointer to the host key filename

Returns:

GLOBUS_SUCCESS if the host cert and key were found, otherwise an error object identifier is returned

globus_result_t globus_gsi_sysconfig_get_service_cert_filename_unix	(	char *	service_name,
		char **	service_cert,
		char **	service_key
	)

Get the Service Certificate Filename based on the current user's environment.

The host cert and key are searched for in the following locations (in order):

1. X509_USER_CERT and X509_USER_KEY environment variables
2. \/etc\/grid-security\/{service_name}\/{service_name}[cert|key].pem
3. GLOBUS_LOCATION\/etc\/{service_name}\/{service_name}[cert|key].pem So for example, if my service was named: myservice, the location of the certificate would be: GLOBUS_LOCATION\/etc\/myservice\/myservicecert.pem
4. \<users home\>\/.globus\/{service_name}\/{service_name}[cert|key].pem

Parameters:

service_name	The name of the service which allows us to determine the locations of cert and key files to look for
service_cert	pointer to the host certificate filename
service_key	pointer to the host key filename

Returns:

GLOBUS_SUCCESS if the service cert and key were found, otherwise an error object identifier

globus_result_t globus_gsi_sysconfig_get_proxy_filename_unix	(	char **	user_proxy,
		globus_gsi_proxy_file_type_t	proxy_file_type
	)

Get the proxy cert filename based on the following search order:

1. X509_USER_PROXY environment variable - This environment variable is set by the at run time for the specific application. If the proxy_file_type variable is set to GLOBUS_PROXY_OUTPUT (a proxy filename for writing is requested), and the X509_USER_PROXY is set, this will be the resulting value of the user_proxy filename string passed in. If the proxy_file_type is set to GLOBUS_PROXY_INPUT and X509_USER_PROXY is set, but the file it points to does not exist, or has some other readability issues, the function will continue checking using the other methods available.

2. Check the default location for the proxy file of \/tmp\/x509_u\<user_id\> where \<user id\> is some unique string for that user on the host

Parameters:

user_proxy	the proxy filename of the user
proxy_file_type	Switch for determining whether to return a existing proxy filename or if a filename suitable for creating a proxy should be returned
