The dnaNextValue attribute is required to set up distributed numeric assignment for an attribute.
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 -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=Distributed Numeric Assignment Plugin,
cn=plugins, cn=config
Valid Range Any string
Default Value None
Syntax DirectoryString
Example dnaPrefix: id
3.7 .7. dnaRangeRequest T imeout
One potential situation with the Distributed Numeric Assignment Plug-in is that one server begins to run
out of numbers to assign. T he 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 dnaScope: ou=people,dc=example,dc=com
