Netscape DIRECTORY SERVER 7.0 - PLUG-IN Manual page 82

How Pre/Post-Operation Plug-ins Work
You can also set up the Directory Server to call your own plug-in functions before
and after:
• Sending an LDAP entry back to the client.
• Sending an LDAP result code back to the client.
• Sending an LDAP referral back to the client.
Figure 6-1 illustrates how the Directory Server front-end calls pre-operation and
post-operation functions before and after executing an LDAP operation.
When processing a request, the Directory Server will call all registered
pre-operation functions before it calls the backend to service the request. All
pre-operation functions must return before the front-end calls the associated
backend function.
