Resource and Role Attribute Mappings

Resource attribute can be set by several means: manually specified in midPoint user interface, produced by a mapping in a role or in resource schema handling. MidPoint is designed to automatically merge all the values produced by mappings. This approach is quite clear when applied to multi-valued attributes, where all the results of all mappings are combined together. But it is a different story for single-valued attributes. Only one value can be a result and it is not that obvious how several mappings are combined to produce the value. The following table provides a summary of the values are produced. The table corresponds to the following scenario:

CSV resource
Resource schema mapping to an attribute setting the value to False
Role schema mapping to the same attribute setting the value to True
Resource assigned to a user thus creating an account on the CSV resource
Role assigned to user
Role unassigned from user

The Resource and Role columns show the strength and authoritative settings for the attribute. The Resultant Value columns show the attribute value on the resource after adding the role and removing the role.

Resource	Role	Resultant Value
Strength	Expression	Strength	Expression	Authoritative	Add Role	Remove Role
Weak	FALSE	Weak	TRUE	TRUE	FALSE	FALSE
Weak	FALSE	Normal	TRUE	TRUE	TRUE	Value Erased
Weak	FALSE	Strong	TRUE	TRUE	TRUE	FALSE
Normal	FALSE	Weak	TRUE	TRUE	FALSE	FALSE
Normal	FALSE	Normal	TRUE	TRUE	TRUE	Value Erased
Normal	FALSE	Strong	TRUE	TRUE	TRUE	FALSE
