The Schema Local Backend Workflow Element provides access to the Directory Server schema information, including the attribute types, object classes, attribute syntaxes, matching rules, matching rule uses, DIT content rules, and DIT structure rules that it contains.
The server allows "modify" operations in this backend to alter the server schema definitions. The configuration entry for this backend is based on the ds-cfg-schema-local-backend-workflow-element structural object class. Note that any attribute types included in this entry that are not included in this object class (or the parent ds-cfg-local-backend-workflow-element class) appears directly in the schema entry.
The Schema Local Backend Workflow Element component inherits from the Local Backend Workflow Element
A description of each property follows.
Basic Properties: | Advanced Properties: |
---|---|
↓ base-dn | ↓ java-class |
↓ enabled | ↓ schema-entry-dn |
↓ referrals-url | |
↓ show-all-attributes | |
↓ writability-mode |
Description | Specifies the base DN(s) for the data that the backend handles. A single backend may be responsible for one or more base DNs. Note that no two backends may have the same base DN although one backend may have a base DN that is below a base DN provided by another backend. If any of the base DNs is subordinate to a base DN for another backend, then all base DNs for that backend must be subordinate to that same base DN. |
---|---|
Default Value | None |
Allowed Values | A valid DN. |
Multi-valued | Yes |
Required | Yes |
Admin Action Required | None. No administrative action is required by default although some action may be required on a per-backend basis before the new base DN may be used. |
Advanced Property | No |
Read-only | No |
Description | Indicates whether the Workflow Element is enabled for use in the server. If a Workflow Element is not enabled, then its contents are not accessible when processing operations. |
---|---|
Default Value | None |
Allowed Values | true false |
Multi-valued | No |
Required | Yes |
Admin Action Required | None |
Advanced Property | No |
Read-only | No |
Description | The URLs that should be returned when the server is not able to fulfill the requests. Set of LDAP URLs providing a reference to an alternate location in which an operation may be processed. If not defined, URLs provided by the replication service will be used. |
---|---|
Default Value | None |
Allowed Values | A LDAP URL compliant with RFC 2255. |
Multi-valued | Yes |
Required | No |
Admin Action Required | None |
Advanced Property | No |
Read-only | No |
Description | Indicates whether to treat all attributes in the schema entry as if they were user attributes regardless of their configuration. This may provide compatibility with some applications that expect schema attributes like attributeTypes and objectClasses to be included by default even if they are not requested. Note that the ldapSyntaxes attribute is always treated as operational in order to avoid problems with attempts to modify the schema over protocol. |
---|---|
Default Value | None |
Allowed Values | true false |
Multi-valued | No |
Required | Yes |
Admin Action Required | None |
Advanced Property | No |
Read-only | No |
Description | Specifies the behavior that the backend should use when processing write operations. |
---|---|
Default Value | enabled |
Allowed Values | disabled - Causes all write attempts to fail. enabled - Allows write operations to be performed in that backend (if the requested operation is valid, the user has permission to perform the operation, the backend supports that type of write operation, and the global writability-mode property is also enabled). internal-only - Causes external write attempts to fail but allows writes by replication and internal operations. |
Multi-valued | No |
Required | Yes |
Admin Action Required | None |
Advanced Property | No |
Read-only | No |
Description | Specifies the fully-qualified name of the Java class that provides the Schema Local Backend Workflow Element implementation. |
---|---|
Default Value | org.opends.server.workflowelement.localbackend.SchemaLocalBackendWorkflowElement |
Allowed Values | A java class that implements or extends the class(es) : org.opends.server.workflowelement.WorkflowElement |
Multi-valued | No |
Required | Yes |
Admin Action Required | None |
Advanced Property | Yes |
Read-only | No |
Description | Defines the base DNs of the subtrees in which the schema information is published in addition to the value included in the base-dn property. The value provided in the base-dn property is the only one that appears in the subschemaSubentry operational attribute of the server's root DSE (which is necessary because that is a single-valued attribute) and as a virtual attribute in other entries. The schema-entry-dn attribute may be used to make the schema information available in other locations to accommodate certain client applications that have been hard-coded to expect the schema to reside in a specific location. |
---|---|
Default Value | cn=schema |
Allowed Values | A valid DN. |
Multi-valued | Yes |
Required | No |
Admin Action Required | None |
Advanced Property | Yes |
Read-only | No |
