/**
@brief Implement the "complete" method.
@param ctx The method context.
@return -1 upon error; zero if successful, and if a STATUS message has been sent to the
client to indicate completion; a positive integer if successful but no such STATUS
message has been sent.
Method parameters:
- a hash with some combination of the following elements:
- "username"
- "barcode"
- "password" (hashed with the cached seed; not plaintext)
- "type"
- "org"
- "workstation"
- "agent" (what software/interface/3rd-party is making the request)
- "nonce" optional login seed to differentiate logins using the same username.
The password is required. Either a username or a barcode must also be present.
Return to client: Intermediate authentication seed.
Validate the password, using the username if available, or the barcode if not. The
user must be active, and not barred from logging on. The barcode, if used for
authentication, must be active as well. The workstation, if specified, must be valid.
Upon deciding whether to allow the logon, return a corresponding event to the client.
