Authentication

The package database class provides these methods for logging in to the Unwired Server:

• onlineLogin – authenticates credentials against the Unwired Server.
• offlineLogin – authenticates against the most recent successfully authenticated credentials. Once the client connects for the first time, the server validated username and password are stored locally. offlineLogin verifies with the client database if those credentials are valid. The method returns YES if the username and password are correct, otherwise the method returns NO.
  There is no communication with Unwired Server in this method. This method is useful if there is no connection the the Unwired Server and you want to access the client application locally.
• loginToSync – tries offlineLogin first. offlineLogin authenticates against the last successfully authenticated credential. There is no communication with the Unwired Server in this method. If offlineLogin fails, this method tries onlineLogin.
• beginOnlineLogin – sends the login request asynchronously (it returns without waiting for a server response). See Reference: Administration APIs > Reference > iPhone Client Object API > Synchronization APIs.
