Plug-in Name ACL Preoperation
DN of Configuration Entry cn=ACL preoperation, cn=plugins, cn=config
Description ACL access check plug-in
Configurable Options on | off
Default Setting on

Leave this plug-in enabled since it is the primary
means of access control for the server.
Further Information See the "Managing Access Control" chapter in
the Directory Server Administrator's Guide.
3.1.4 . Attribute Uniqueness Plug-in
Plug-in Parameter Description
Plug-in Name Attribute Uniqueness Plug-in
DN of Configuration Entry cn=Attribute Uniqueness, cn=plugins, cn=config
Description Checks that the values of specified attributes are
unique each time a modification occurs on an
entry. For example, most sites require that a user
ID and email address be unique.
Configurable Options on | off
Default Setting off
Configurable Arguments To check for UID attribute uniqueness in all listed
subtrees, enter uid "DN" "DN".... However,
to check for UID attribute uniqueness when
adding or updating entries with the
requiredObjectClass, enter
attribute="uid" MarkerObjectclass =
"ObjectClassNam e" and, optionally
requiredObjectClass =
"ObjectClassNam e". This starts checking for
the required object classes from the parent entry
containing the ObjectClass as defined by the
MarkerObjectclass attribute.
Dependencies Database
Performance Related Information Directory Server provides the UID Uniqueness
Plug-in by default. To ensure unique values for
other attributes, create instances of the Attribute
Uniqueness Plug-in for those attributes. See the
"Using the Attribute Uniqueness Plug-in" in the
Directory Server Administrator's Guide for more
information about the Attribute Uniqueness Plug-
in.
The UID Uniqueness Plug-in is off by default due
to operation restrictions that need to be
addressed before enabling the plug-in in a multi-
master replication environment. Turning the plug-
in on may slow down Directory Server
performance.
Further Information See the"Using the Attribute Uniqueness Plug-in"
in the Directory Server Administrator's Guide.
3.1.5. Binary Syntax Plug-in
Plug-in Parameter Description
Plug-in Name Binary Syntax
DN of Configuration Entry cn=Binary Syntax, cn=plugins, cn=config
