Dnathreshold; Dnatype - Red Hat DIRECTORY SERVER 8.1 Command Reference Manual

Chapter 3. Plug-in Implemented Server Functionality Reference
NOTE
The shared configuration entry must be configured in the replicated
subtree, so that the entry can be replicated to the servers. For example,
if the ou=People,dc=example,dc=com subtree is replicated, then the
configuration 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 will
automatically contain a sub-entry beneath it to transfer ranges.

3.7.10. dnaThreshold

One potential situation with the Distributed Numeric Assignment Plug-in is that one server begins to
run out of numbers to assign, which can cause problems. The Distributed Numeric Assignment Plug-in
allows 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, the
dnaThreshold attribute sets a threshold of remaining available numbers in the range. When the
server hits the threshold, it sends a request for a new range.
For range requests to be performed, the dnaSharedCfgDN attribute must be set.

3.7.11. dnaType

This attribute sets which attribute has unique numbers being generated for it. In this case, whenever
the attribute is added to the entry without a value or with the magic number, an assigned value is
automatically supplied.
