3.7.5. dnaNextValue
This attribute gives the next available number which can be assigned. After being initially set in the

The dnaNextValue attribute is required to set up distributed numeric assignment for an attribute.
Parameter

cn=plugins, cn=config
Valid Range
1 to the maximum 32-bit integer on 32-bit systems
and to the maximum 64-bit integer on 64-bit
systems
Default Value
-1
Syntax
Integer
Example
dnaNextValue: 1
3.7.6. dnaPrefix
This attributes defines a prefix that can be prepended to the generated number values for the attribute.
For example, to generate a user ID such as user1000, the dnaPrefix setting would be user.
Parameter
Description
Entry DN

cn=plugins, cn=config
Valid Range

Default Value
None
Syntax
DirectoryString
Example

3.7.7. dnaRangeRequestTimeout
One potential situation with the Distributed Numeric Assignment Plug-in is that one server begins to run
out of numbers to assign. The dnaThreshold attribute sets a threshold of available numbers in the
range, so that the server can request an additional range from the other servers before it is unable to
perform number assignments.
The dnaRangeRequestTimeout attribute sets a timeout period, in seconds, for range requests so that
the server does not stall waiting on a new range from one server and can request a range from a new
server.
For range requests to be performed, the dnaSharedCfgDN attribute must be set.
Parameter
Description
Entry DN
cn=Distributed Numeric Assignment Plugin,
cn=plugins, cn=config
Valid Range
1 to the maximum 32-bit integer on 32-bit systems
and to the maximum 64-bit integer on 64-bit
systems
Default Value
10
Syntax
Integer
Example
dnaRangeRequestTimeout: 15
3.7.8. dnaScope
This attribute sets the base DN to search for entries to which to apply the distributed numeric
assignment. This is analogous to the base DN in an ldapsearch.
Parameter
Description
Entry DN
cn=Distributed Numeric Assignment Plugin,
cn=plugins, cn=config
Valid Range
Any Directory Server entry
Default Value
None
Syntax
DirectoryString
Example
