Processing an LDAP Search Operation
The server processes an LDAP search operation in two stages:
•
First, the server gets a list of candidate entries, using an index (if applicable).
For example, for a search filter that finds entries where "
checks the index for the "
start with "
If no applicable index exists, all entries are considered to be candidates.
To get the list of candidates, the server calls the backend search function. For
details, see "Getting the List of Candidates" on page 81.
•
Next, the server iterates through each candidate in the list and determines if
the candidate matches the search criteria.
If an entry matches the criteria, the server sends the entry to the client.
To check each candidate, the server calls the backend "next candidate"
function for each candidate in the list. For details, see "Iterating Through
Candidates" on page 82.
The rest of this section explains these stages in more detail.
