### 2.2.19. Hints For the SAE Authentication Module

The Secure Attribute Exchange (SAE) module lets OpenAM authenticate a user who has already authenticated with an entity that can vouch for the user to OpenAM, so that OpenAM creates a session for the user. This module is useful in virtual federation, where an existing entity instructs the local OpenAM instance to use federation protocols to transfer authentication and attribute information to a partner application.

  Sets the authentication level used to indicate the level of security associated with the module. The value can range from 0 to any positive integer.
