The following citation contains a timeline of when each method value was introduced.<59>

Note Gaps in the opnum numbering sequence represent opnums of methods that are specified in [MS-LSAT], or opnums that MUST NOT be used over the wire.<60>

Note Exceptions MUST NOT be thrown beyond those thrown by the underlying RPC protocol (as specified in [MS-RPCE]), unless otherwise specified.

The return values of all methods MUST conform to the specification of NTSTATUS, as specified in [MS-ERREF] section 2.3. Specific return values for normative processing conditions are specified in this document in the subsections of this section.

Unless otherwise specified, all negative values returned by an implementation are treated equivalently by the client as a message processing error. Unless otherwise specified, all non-negative values returned by an implementation are treated equivalently by the client as a success (of message processing).

Return values for implementation-specific conditions are left to the implementer's discretion, subject to the constraints specified in [MS-ERREF]. For example, an implementation can re-use an existing value in [MS-ERREF], such as 0xC0000017 (no memory).

All methods in this protocol MUST perform data validation (as specified in section 3.1.4.10) for all parameters that are specified as input parameters. If data validation fails for some reason, processing MUST end, and the server MUST respond back with a failure.

In the following sections, the first general idea behind the common operations is explained in sections 3.1.4.1, 3.1.4.2, and 3.1.4.3. The methods are grouped by functionality: policies, accounts, secrets, trusted domains, privileges, and common object methods. Section 3.1.4.10 explains the data validation rules.
