The Unique Attribute Plugin enforces constraints on the value of an attribute within a portion of the directory.
The values for each attribute must be unique within each base DN specified in the plugin's base-dn property or within all of the server's public naming contexts if no base DNs were specified.
The Unique Attribute Plugin component inherits from the Plugin
A description of each property follows.
| Basic Properties: | Advanced Properties: |
|---|---|

| Multi-valued | No |
| Required | Yes |
| Admin Action Required | None |
| Advanced Property | Yes |
| Read-only | No |
| Description | Specifies the set of plug-in types for the plug-in, which specifies the times at which the plug-in is invoked. |
| Default Value | preoperationadd
preoperationmodify
preoperationmodifydn
postoperationadd
postoperationmodify
