Chapter 3. Plug-in Implemented Server Functionality Reference208NOTEThe shared configuration entry must be configured in the replicatedsubtree, so that the entry can be replicated to the servers. For example,if the ou=People,dc=example,dc=com subtree is replicated, then theconfiguration entry must be in that subtree, such as ou=UID Number Ranges,ou=People,dc=example,dc=com.The entry identified by this setting must be manually created by the administrator. The server willautomatically contain a sub-entry beneath it to transfer ranges.Parameter DescriptionEntry DN cn=Distributed Numeric Assignment Plugin,cn=plugins, cn=configValid Range Any DNDefault Value NoneSyntax DNExample dnaSharedCfgDN: cn=range transfer user,cn=config3.7.10. dnaThresholdOne potential situation with the Distributed Numeric Assignment Plug-in is that one server begins torun out of numbers to assign, which can cause problems. The Distributed Numeric Assignment Plug-inallows the server to request a new range from the available ranges on other servers.So that the server can recognize when it is reaching the end of its assigned range, thednaThreshold attribute sets a threshold of remaining available numbers in the range. When theserver hits the threshold, it sends a request for a new range.For range requests to be performed, the dnaSharedCfgDN attribute must be set.Parameter DescriptionEntry DN cn=Distributed Numeric Assignment Plugin,cn=plugins, cn=configValid Range 1 to the maximum 32-bit integer on 32-bitsystems and to the maximum 64-bit integer on64-bit systemsDefault Value 100Syntax IntegerExample dnaThreshold: 1003.7.11. dnaTypeThis attribute sets which attribute has unique numbers being generated for it. In this case, wheneverthe attribute is added to the entry without a value or with the magic number, an assigned value isautomatically supplied.
