025 /**
026 * Control which allows for the management of referrals and other DSA specific
027 * entities without processing them: meaning the referrals are treated as
028 * regular entries using this control. More information is available in <a
029 * href="">RFC 3296</a>. Below we have included section 3 of the RFC describing
030 * this control:
031 *
032 * <pre>
033 * 3. The ManageDsaIT Control
034 *
035 * The client may provide the ManageDsaIT control with an operation to
036 * indicate that the operation is intended to manage objects within the
037 * DSA (server) Information Tree. The control causes Directory-specific
038 * entries (DSEs), regardless of type, to be treated as normal entries
039 * allowing clients to interrogate and update these entries using LDAP
040 * operations.
041 *
042 * A client MAY specify the following control when issuing an add,
043 * compare, delete, modify, modifyDN, search request or an extended
044 * operation for which the control is defined.
045 *
046 * The control type is 2.16.840.1.113730.3.4.2. The control criticality
047 * may be TRUE or, if FALSE, absent. The control value is absent.
048 *
049 * When the control is present in the request, the server SHALL NOT
050 * generate a referral or continuation reference based upon information
051 * held in referral objects and instead SHALL treat the referral object
052 * as a normal entry. The server, however, is still free to return
053 * referrals for other reasons. When not present, referral objects
054 * SHALL be handled as described above.
055 *
056 * The control MAY cause other objects to be treated as normal entries
057 * as defined by subsequent documents.
058 * </pre>
