This query is used by lookup in the LDAP driver. The first “-g” tells BIND to write all log messages to stdout instead of a log file. The query must use the correct pre-defined tokens. The last parameter is “data”. Some of the DLZ drivers allow the use of “default values”. This query is used by authority in the LDAP driver.

You can download the LDAP source from www. Our driver knows that NS1 is relative to the zone we are searching in. Your database can hold these attributess as strings or numbers, but they MUST be able to be properly parsed into a number without any extra characters. For example, if we had an all nodes query that returned 12 attributes, the entry for a mx record might have the following data:.

Package: dlz-ldap-enum (1.1.0-1)

The diagrams below demonstrate the two tree structures. The attributes must be in that order, and the data attribute or attributes concatenated together must hold the remainder of any data required for that DNS record type.

The driver does NOT release connections during periods of inactivity and then re-open them when needed. Also, the number of attributes returned by the lookup query can very from 3 to an unlimited number. There are five queries that can be used by the LDAP driver.

This configuration segment would be contained in BIND’s config named. Notice ddlz are no characters or spaces between the brackets. As with the allnodes query, append a “. This is correct behavior! This can be very helpful in debugging queries while you are setting up the driver.

Notice the extra “. This parameter is optional and always located at argv[9].

If an attribute returned by the allnodes query is NULL, nothing is appended by that attribute. Run a few sample DNS ldpa to see the queries that are used. This driver has been built specifically to avoid that problem. This makes it easy to manage our DNS data in the database using separate attributes for zone and host names.

It is used in any error messages BIND displays while parsing its config file. The chart below shows 12 attributes but not all attributes are required in all queries. This tells BIND that the domain name is absolute and not to be used relative to our zone of “example. The first “-g” tells BIND to write all log messages to stdout instead of a log file. The values of the attributes may be held as integers, floats, whatever by the database, but the return from the OpenLDAP functions is only a string.


This is done to make the configuration segment easier to read. The sample uses a custom schema developed for DLZ.

lsap In this sample query, we are artificially preventing NS and SOA records from being returned by the query so that we can show the use of the authority function later in this document. The MySQL documentation has a list of which systems are built single threaded by default.

LDAP only really returns strings from a query. The next section “ldap zone” is the label for this configuration segment. Now that we have covered all the different types of queries that can be used by the LDAP driver, we can discuss the number, type and order of attributes returned by the queries. Just like the allnodes query, the first attribute in the entry MUST be the ttl.

This query is used by allnodes in the LDAP driver. Attribute 1 is the left most attribute in a query.
