Authenticating a User to a Node
To authenticate itself to the Open Directory for the purposes of reading, writing, or making changes to a node, an Open Directory client application calls dsDoDirNodeAuth. The dsDoDirNodeAuth function handles authentication methods that use one or more steps to complete the authentication process.
To determine the authentication methods that a node supports, call dsGetDirNodeInfo for the node and request the kDSNAttrAuthMethod attribute. For any particular user, some methods may not be supported. The available authentication methods depend on the authentication authority of the user that is being authenticated.
