(Not applicable to Online Data Proxy) The SAP implementation uses the same control flag (controlFlag) attribute values and definitions as those defined in the JAAS specification.
If you stack multiple providers, you must set the control flag attribute for each enabled provider.
|Control Flag Value||Description|
|Required||The LoginModule is required. Authentication proceeds down the LoginModule list.|
|Requisite||The LoginModule is required. Subsequent behavior depends on the authentication result:
|Sufficient||The LoginModule is not required. Subsequent behavior depends on the authentication result:
|Optional (default)||The LoginModule is not required. Regardless of success or failure, authentication proceeds down the LoginModule list.|
Providers are listed in this order and with these controlFlag:
A client doing certificate authentication (for example, X.509 SSO to SAP) can authenticate immediately. Subsequent modules are not called, because they are not required. If there are regular user name and password credentials, they go to LDAP, which may authenticate them, and set them up with roles from the LDAP groups they belong to. Then NativeOS is invoked, and if that succeeds, SAP Mobile Platform picks up roles based on the Windows groups they are in.
