Configuring identity federation configuration

An apparatus for configuring identity federation configuration, comprising:

• a processor;
• and
• a memory, comprising:
• an acquisition module, configured to acquire a first set of identity federation configuration properties of a first computing system and a second set of identity federation configuration properties of a second computing system;
• an association module, configured to identify one or more pairs of associated properties in the first and the second sets of identity federation configuration properties, wherein each of the pairs of associated properties includes one property from the first set of identity federation configuration properties and one property from the second set of identity federation configuration properties;
• a user interaction module, configured to display, in a unified user interface, properties that need to be configured manually from the first and the second sets of identity federation configuration properties, wherein the properties that need to be configured manually do not include the property in any pair of associated properties for which the value can be derived from the value of another property in the pair;
• a cross-assignment module, configured to automatically assign a value to an property for which the value can be derived from the value of another property;
• and
• a configuration adapter, configured to provide the first and the second computing systems respectively with the first set of identity federation properties and the second set of identity federation properties that have been configured.
