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.
Parameter Description
Entry DN cn=config, cn=ldbm database, cn=plugins,
cn=config
Valid Range -1 to maximum 32-bit integer in entries (where -1
is unlimited)
Default Value 5000
Syntax Integer
Example nsLookThroughLimit: 5000
3.4.1.2. nsslapd-idlistscanlimit
This performance-related attribute, present by default, specifies the number of entry IDs that are
searched during a search operation. 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.
It is advisable to keep the default value to improve search performance. For a more detailed
explanation of the effect of ID lists on search performance, refer to the "Managing Indexes" chapter in
the Directory Server Administrator's Guide.
The server has to be restarted for changes to this attribute to go into effect.
Parameter Description
Entry DN cn=config, cn=ldbm database, cn=plugins,
cn=config
Valid Range 100 to the maximum 32-bit integer value
(2147483647) entry IDs
Default Value 4000
Syntax Integer
Example nsslapd-idlistscanlimit: 4000
3.4.1.3. nsslapd-cache-autosize
This performance tuning-related attribute, which is turned off by default, specifies the percentage of
free memory to use for all the combined caches. For example, if the value is set to 80, then 80 percent
of the remaining free memory would be claimed for the cache. To run other servers on the machine,
then set the value lower. Setting the value to 0 turns off the cache autosizing and uses the normal
nsslapd-cachememsize and nsslapd-dbcachesize attributes.
