+ testpreop.c
+
+ This source file provides examples of pre-operation plug-in
+ functions.  The server calls these plug-in functions before
+ executing certain LDAP operations:
+
+ * testpreop_bind (called before an LDAP bind operation)
+ * testpreop_add (called before an LDAP add operation)
+ * testpreop_abandon (called before an LDAP abandon operation)
+
+ testpreop_bind logs information about the LDAP bind operation
+ to the server error log.  testpreop_add prepends the name "BOB"
+ to the value of the cn attribute before an entry is added.  
+
+ Note that the Directory Server front-end handles bind
+ operations requested by the root DN. The server does not
+ invoke your plug-in function if the client is authenticating 
+ as the root DN. 
+
+ To test this plug-in function, stop the server, edit the dse.ldif file
+ (in the <server_root>/slapd-<server_id>/config directory)
+ and add the following lines before restarting the server :
+
+ dn: cn=Test Preop,cn=plugins,cn=config
+ objectClass: top
+ objectClass: nsSlapdPlugin
+ objectClass: extensibleObject
+ cn: Test Preop
+ nsslapd-pluginPath: <server_root>/plugins/slapd/slapi/examples/libtest-plugin.so
+ nsslapd-pluginInitfunc: testpreop_init
+ nsslapd-pluginType: preoperation
+ nsslapd-pluginEnabled: on
