3.4. Database Plug-in Attributes
The database plug-in is also organized in an information tree, as shown in
Figure 3.1, “Database Plug-
in”
.
Figure 3.1. Database Plug-in
All plug-in technology used by the database instances is stored in the
cn=ldbm database
plug-in
node. This section presents the additional attribute information for each of the nodes in bold in the
cn=ldbm database, cn=plugins, cn=config
information tree.
3.4.1. Database Attributes under cn=config, cn=ldbm database,
cn=plugins, cn=config
This section covers global configuration attributes common to all instances are stored in the
cn=config, cn=ldbm database, cn=plugins, cn=config
tree node.
3.4.1.1. nsLookThroughLimit
This performance-related attribute specifies the maximum number of entries that the Directory Server
will check when examining candidate entries in response to a search request. The Directory Manager
DN, however, is, by default, unlimited and overrides any other settings specified here. It is worth noting
that binder-based resource limits work for this limit, which means that if a value for the operational
attribute
nsLookThroughLimit
is present in the entry as which a user binds, the default limit
will be overridden. Attempting to set a value that is not a number or is too big for a 32-bit signed
integer returns an
LDAP_UNWILLING_TO_PERFORM
error message with additional error information
explaining the problem.
