Thank you Rich for this fast and precious help, In the main samples I found the 'ldap_create_persistentsearch_control' is followen by a 'ldap_search_ext' and its while loop to parse the result and the entry to have the different type of changes that occured on the 'watched' node. This method costs CPU, as it is not a ponctual operation (like a read or write call). Do I have to include a 'sleep' call in the loop ? Or is there any other manner to wait for the event ?
Any detail on 'last change number' to resychronize the servers with the NDS ? Many thanks. Hedi.
