@NotMutable @ThreadSafety(level=COMPLETELY_THREADSAFE) public final class PermissiveModifyRequestControl extends Control
This class provides an implementation of the permissive modify request control, which is supported by a number of servers and may be included in a modify request to indicate that the server should not reject a modify request which attempts to add an attribute value which already exists or remove an attribute value which does not exist. Normally, such modification attempts would be rejected.
The OID for this control is "1.2.840.113556.1.4.1413". It does not have a value.
Example
The following example demonstrates the use of the permissive modify request control to process a modification that attempts to add an attribute value to an entry that already contains that value.// Ensure that we start with a known description value in the test entry // by using a replace to overwrite any existing value(s). ModifyRequest replaceRequest = new ModifyRequest( "uid=test.user,ou=People,dc=example,dc=com", new Modification(ModificationType.REPLACE, "description", "value")); LDAPResult replaceResult = connection.modify(replaceRequest); // Create a modify request that will attempt to add the value that already // exists. If we attempt to do this without the permissive modify control, // the attempt should fail. ModifyRequest addExistingValueRequest = new ModifyRequest( "uid=test.user,ou=People,dc=example,dc=com", new Modification(ModificationType.ADD, "description", "value")); LDAPResult addExistingValueResultWithoutControl; try { addExistingValueResultWithoutControl = connection.modify(addExistingValueRequest); // We shouldn't get here because the attempt to add the existing value // should fail. } catch (LDAPException le) { // We expected this failure because the value we're trying to add already // exists in the entry. addExistingValueResultWithoutControl = le.toLDAPResult(); ResultCode resultCode = le.getResultCode(); String errorMessageFromServer = le.getDiagnosticMessage(); } // Update the modify request to include the permissive modify request // control, and re-send the request. The operation should now succeed. addExistingValueRequest.addControl(new PermissiveModifyRequestControl()); LDAPResult addExistingValueResultWithControl; try { addExistingValueResultWithControl = connection.modify(addExistingValueRequest); // If we've gotten here, then the modification was successful. } catch (LDAPException le) { // If we've gotten here, then the modification failed for some reason. addExistingValueResultWithControl = le.toLDAPResult(); ResultCode resultCode = le.getResultCode(); String errorMessageFromServer = le.getDiagnosticMessage(); }
