To define a new computed ID data connector, create a <DataConnector xsi:type="dc:StoredId" xmlns="urn:mace:shibboleth:2.0:resolver:dc"> element with the following attributes:
- id - a unique identifier for the data connector
- sourceAttributeID - the ID of an attribute, provided by a dependency, whose first value will be used within the computed ID hash
- generatedAttributeID - name of the attribute produced by this data connector. optional, defaults to
storedId salt - a string of random data; must be at least 16 characters, 48 characters is recommended. Be sure to write down this salt value somewhere safeso that the persistentIDs are not lost if you delete your configuration file!
Note It is recommended that the attribute given by
sourceAttributeIDbe a non-reassigned value, unique to each user. Usage of such a value effectively eliminates problems that may occur if a value is re-assigned and a service provider has not cleaned out state from the previous owner of that ID.Code Block xml title Basic Stored ID Data Connector xml <resolver:DataConnector xsi:type="dc:StoredId" xmlns="urn:mace:shibboleth:2.0:resolver:dc" id="UNIQUE_ID" generatedAttributeID="OUTPUT_UNIQUE_ID" sourceAttributeID="SOME_ID" salt="ThisIsRandomText"> <!-- Remaining configuration from the next steps go here --> </resolver:DataConnector>
