Java/CORBA LDAP Schema Tools This note describes the tools for creating schema entries for storing Java and CORBA objects. The Java schema is described in RFC 2713. http://www.ietf.org/rfc/rfc2713.txt The CORBA schema is described in RFC 2714. http://www.ietf.org/rfc/rfc2714.txt 1. UPDATING THE DIRECTORY SCHEMA You can use your directory's administration tool to update the schema, Or, you can use the CreateJavaSchema and CreateCorbaSchema programs. java [-Djava.naming.provider.url=] \ CreateCorbaSchema|CreateJavaSchema \ [-h|-s[n]] [-n] [-p] [-a] -h Print the usage message -l List the relevant 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 Use as the distinguished name for authentication -p Use as the password for authentication -a Use as the authentication mechanism. Default is "simple". If neither -s, -l, nor -h has been specified, the default is "-l". NOTE: If you are using Netscape Directory Server 4.0 (or earlier), you need to use the "-sn" option to workaround schema bugs in the server. NOTE: If you are using Netscape Directory Server 4.1, you need to use the "-sn41" option to workaround schema bugs in the server. Also, before making any changes to the schema, you must make the following schema modification. Locate the ns-schema.conf file in the server installation at the directory named: /slapd-/config/ Comment out the line that contains 'java-object-schema.conf' because that schema is now out-of-date. Then re-start the server and use the CreateJavaSchema program to install the updated schema. It is necessary to manually remove the reference to the old schema from the list of built-in schemas in ns-schema.conf because the server does not permit such built-in schemas to be modified via the LDAP protocol. NOTE: If you are using Microsoft Active Directory you need to use the "-sad" option to workaround schema bugs in the server. Also, to enable any schema modifications the following registry property must be created and set to (DWORD) 1: HKEY_LOCAL_MACHINE System CurrentControlSet Services NTDS 参数 Schema Update Allowed If the directory's administration tool supports turning off schema checking then do so before running the CreateJavaSchema or CreateCorbaSchema programs. When you run these programs, you need to login as the directory administrator, quoting the "-n" option if there are blanks in the distinguished name. After updating the schema, you should use the directory server's administration tool to verify that the changes have been properly applied. The Netscape Directory Server 3.0, for example, ignores some attributes. If the schema has not been properly updated, use the administration tool to correct it. For example, to create the Java schema in a Netscape Directory Server version 4.1, java -Djava.naming.provider.url=ldap://myserver CreateJavaSchema\ -sn41 "-ncn=Directory Administrator" -psecret For example, to create the CORBA schema in a Netscape Directory Server version 4.0, java -Djava.naming.provider.url=ldap://myserver CreateCorbaSchema\ -sn "-ncn=Directory Administrator" -psecret For example, to create the Java schema in a Windows 2000 Active Directory, java -Djava.naming.provider.url=ldap://myserver CreateJavaSchema\ -sad "-ncn=administrator,cn=users,dc=xxx,dc=yyy,dc=zzz" -psecret ----
