Describes an attribute of an object.


Property Type Description
anchor Boolean true if the attribute should be used as the anchor for the object. Anchor attributes must have a unique value identifying an object, and must be immutable. Default is false. One, and only one, of the object's attributes must be designated as the anchor to support synchronization.
caseExact Boolean true if value of this attribute should be treated as case-sensitive. This setting affects how the synchronization engine detects changes for the attribute.
flowNullValues Boolean 'true' to allow null values for attributes.
metadata metadataEntry collection Additional extension properties. Unless mentioned explicitly, metadata values should not be changed.
multivalued Boolean true if an attribute can have multiple values. Default is false.
mutability mutability An attribute's mutability. Possible values are: ReadWrite, ReadOnly, Immutable, WriteOnly. Default is ReadWrite.
name String Name of the attribute. Must be unique within the object definition. Not nullable.
required Boolean true if attribute is required. Object can not be created if any of the required attributes are missing. If during synchronization, the required attribute has no value, the default value will be used. If default the value was not set, synchronization will record an error.
referencedObjects referencedObject collection For attributes with reference type, lists referenced objects (for example, the manager attribute would list User as the referenced object).
type attributeType Attribute value type. Possible values are: String, Integer, Reference, Binary, Boolean,DateTime. Default is String.
