The plug-in function is called by the server when the server is configured to use the null dn. meaning dn: The server uses the null dn or the root suffix opnly when the configuration for the server has the following node in the dse.ldif of the server instance (in the /slapd-/config directory). dn: cn="",cn=mapping tree,cn=config objectClass: top objectClass: extensibleObject objectClass: nsMappingTree cn: "" nsslapd-state: container The plugin below is a pre-operation plugin which provides alternate functionality for the LDAP operations of search, modify, add etc. that are targeted at the root-suffix or the null-dn to be serviced by an alternate data source or alternate access methods allowing datainteroperability. The example below creates a berkely db and modifies or adds data to the db demonstarting the use of an alternate data source seperate from the Directory Server. Also, the results of a search operation are completely in the control of the pre-operation plugin. In this example a fake entry is returned to express the functionality To test this plug-in function, stop the server, edit the dse.ldif file (in the /slapd-/config directory) and add the following lines before restarting the server : dn: cn="",cn=mapping tree,cn=config objectClass: top objectClass: extensibleObject objectClass: nsMappingTree cn: "" nsslapd-state: container dn: cn=datainterop,cn=plugins,cn=config objectClass: top objectClass: nsSlapdPlugin cn: datainterop nsslapd-pluginPath: /plugins/slapd/slapi/examples/libtest-plugin.so nsslapd-pluginInitfunc: nullsuffix_init nsslapd-pluginType: preoperation nsslapd-pluginEnabled: on nsslapd-pluginId: nullsuffix-preop nsslapd-pluginVersion: 6.2 nsslapd-pluginVendor: Netscape nsslapd-pluginDescription: sample pre-operation null suffix plugin ******************************************/ #include #include #include "slapi-plugin.h" /* * Macros. */ #define PLUGIN_NAME "nullsuffix-preop" #define PLUGIN_OPERATION_HANDLED 1 #define PLUGIN_OPERATION_IGNORED 0 #define SEARCH_SCOPE_ANY (-1) /* * Static variables. */ static Slapi_PluginDesc plugindesc = { PLUGIN_NAME, "Netscape", "0.5", "sample pre-operation null suffix plugin" };
