MQZ_GET_EXPLICIT_AUTHORITY (Get explicit authority) on IBM i

This function is provided by a MQZAS_VERSION_1 authorization service component, and is invoked by the queue manager to retrieve the authority that a named group has to access a specified object (but without the additional authority of the nobody group), or the authority that the primary group of the named principal has to access a specified object.

The function identifier for this function (for MQZEP) is MQZID_GET_EXPLICIT_AUTHORITY.

Syntax

MQZ_GET_EXPLICIT_AUTHORITY (QMgrName, EntityName, EntityType,

ObjectName, ObjectType, Authority, ComponentData, Continuation, CompCode, Reason)

Parameters

The MQZ_GET_EXPLICIT_AUTHORITY call has the following parameters.

QMgrName (MQCHAR48) - input

Queue manager name.

The name of the queue manager calling the component. This name is padded with blanks to the full length of the parameter; the name is not terminated by a null character.

The queue manager name is passed to the component for information; the authorization service interface does not require the component to make use of it in any defined manner.

EntityName (MQCHAR12) - input

Entity name.

The name of the entity from which access to the object is to be retrieved. The maximum length of the string is 12 characters; if it is shorter than that it is padded to the right with blanks. The name is not terminated by a null character.

EntityType (MQLONG) - input

Entity type. The type of entity specified by EntityName. The following value can be specified:

MQZAET_PRINCIPAL

Principal.

MQZAET_GROUP

Group.

ObjectName (MQCHAR48) - input

Object name.

The name of the object for which the entity's authority is to be retrieved. The maximum length of the string is 48 characters; if it is shorter than that it is padded to the right with blanks. The name is not terminated by a null character.

If ObjectType is MQOT_Q_MGR, this name is the same as QMgrName.

ObjectType (MQLONG) - input

Object type. The type of entity specified by ObjectName. It is one of the following:

MQOT_AUTH_INFO

Authentication information.

MQOT_CHANNEL

Channel.

MQOT_CLNTCONN_CHANNEL

Client connection channel.

MQOT_LISTENER

Listener.

MQOT_NAMELIST

Namelist.

MQOT_PROCESS

Process definition.

MQOT_Q

Queue.

MQOT_Q_MGR

Queue manager.

MQOT_SERVICE

Service.

Authority (MQLONG) - output

Authority of entity.

If the entity has one authority, this field is equal to the appropriate authorization operation (MQZAO_* constant). If it has more than one authority, this field is the bitwise OR of the corresponding MQZAO_* constants.

ComponentData (MQBYTE x ComponentDataLength) - input/output

Component data.

This data is kept by the queue manager on behalf of this particular component; any changes made to it by any of the functions provided by this component are preserved, and presented the next time one of this component's functions is called.

The length of this data area is passed by the queue manager in the ComponentDataLength parameter of the MQZ_INIT_AUTHORITY call.

Continuation (MQLONG) - output

Continuation indicator set by component. The following values can be specified:

MQZCI_DEFAULT

Continuation dependent on queue manager.

For MQZ_GET_EXPLICIT_AUTHORITY this has the same effect as MQZCI_CONTINUE.

MQZCI_CONTINUE

Continue with next component.

MQZCI_STOP

Do not continue with next component.

CompCode (MQLONG) - output

Completion code. It is one of the following:

MQCC_OK

Successful completion.

MQCC_FAILED

Call failed.

Reason (MQLONG) - output

Reason code qualifying CompCode. If CompCode is MQCC_OK:

MQRC_NONE

(0, X'000') No reason to report.

If CompCode is MQCC_FAILED:

MQRC_NOT_AUTHORIZED

(2035, X'7F3') Not authorized for access.

MQRC_SERVICE_ERROR

(2289, X'8F1') Unexpected error occurred accessing service.

MQRC_SERVICE_NOT_AVAILABLE

(2285, X'8ED') Underlying service not available.

MQRC_UNKNOWN_ENTITY

(2292, X'8F4') Entity unknown to service.
