 * Creates the schema for storing CORBA object references according
 * to RFC 2714. After running this program, you should verify that
 * the schema has been updated correctly by using the directory server's
 * administration tool. If the schema has not been properly updated,
 * use the administration tool to correct it.
 *
 * You should first turn off schema-checking at the directory server 
 * before running this program.
 *
 * usage:
 * java [-Djava.naming.provider.url=<ldap_server_url>] \
 *     CreateCorbaSchema [-h|-l|-s[n|n41|ad]] [-n<dn>] [-p<passwd>] [-a<auth>] 
 *      
 * -h		Print the usage message
 *
 * -l		List the CORBA schema in the directory
 *
 * -s[n|n41|ad]	Update schema:
 *                -sn   means use a workaround for schema bugs in
 *                      pre-4.1 releases of Netscape Directory Server;
 *
 *		  -sn41 means use a workaround for schema bugs in
 *                      Netscape Directory Server version 4.1;
 *
 *		  -sad  means use a workaround for schema bugs in
 *                      Microsoft Windows 2000 Active Directory
 *
 * -n<dn> 	Use <dn> as the distinguished name for authentication
 *
 * -p<passwd>	Use <passwd> as the password for authentication
 *
 * -a<auth>	Use <auth> as the authentication mechanism. Default is "simple".
 *
 *
 * If neither -s, -l, nor -h has been specified, the default is "-l".
 *
 * The following example inserts the CORBA schema from RFC 2714 in a
 * Netscape Directory (using the workaround for 4.1 schema bugs),
 * logging in as "cn=directory manager" with the password "secret".
