Fetching User Attribute Values

The getQnAValues operation is used to read the values that are set for the user attributes present in the directory service. You can fetch the values for one or more attributes. This section walks you through the following steps related to this operation:

Preparing the Request Message
Invoking the Web Service
Interpreting the Response Message

Preparing the Request Message

The following table lists the elements of the QnAValuesRequest message.

Element	Mandatory	Description
username	Yes	The unique identity of the user whose attribute values you want to fetch.
orgname	Yes	The name of the LDAP organization to which the user attribute values that you want to fetch belong.
attributes/attribute	Yes	The name of the attributes whose value you want to fetch.
clientTxId	No	The unique transaction identifier that your calling application can include. This identifier helps in tracking the related transactions.

Invoking the Web Service

To fetch the values of user attributes:

(Optional) Include the authentication and authorization details in the header of the getQnAValues operation. See "Managing Web Services Security" for more information on the header elements.
Use the getQnAValuesRequest elements to collect the user, organization, and attribute information, as listed in the table.
Use the QnAValuesRequest message and construct the input message by using the details specified in the preceding step.
Invoke the getQnAValues operation of the ArcorUserRegistrySvc service to fetch the values of the user attributes that are stored in directory service.
This operation returns the QnAValuesResponse message that includes the transaction identifier, authentication token, and attribute values. See the following section for more information on the response message.

Interpreting the Response Message

The response message, QnAValuesResponse, returns the transaction identifier and the authentication token in the SOAP envelope header. The SOAP body includes the user attribute values for a successful transaction and the Fault response for an error condition.

See the following table for more information on the elements returned for a successful transaction. Refer to appendix, "Exceptions and Error Codes" if there are any errors.

Element	Description

Header Elements
udsTransactionID	The unique identifier of the transaction performed by using UDS.
authToken	The authentication token that is returned if the credential verification to access the Web service was successful. This token eliminates the need for you to present the authentication credential for successive access to the Web service. By default, the authentication token is valid for one day, after which you need to authenticate again.
Body Elements
The values for the user attributes that are configured in the directory service.
