OPTIONAL

The assertion parameter is optional, and can be specified by the client role of the OAuth 2.0 Protocol Extensions in the POST body when making a request to the token endpoint (section 3.2.5.2). The client provides an access token previously received from the AD FS server in the assertion parameter when making an OAuth on-behalf-of request or an OAuth logon certificate request.

The AD FS server ignores this parameter unless its ad_fs_behavior_level is AD_FS_BEHAVIOR_LEVEL_2 or higher.

For an example of the assertion parameter being used, see section 4.7.

The format for the assertion parameter is as follows.

 String = *(%x20-7E)
 assertion = String
