This is the only protocol that's available on the authentication server. Other protocols are only available on the secure server.

Method ID	Name (Wii U)	Name (Switch)
1	Login	ValidateAndRequestTicket
2	LoginEx	ValidateAndRequestTicketWithCustomData
3	RequestTicket	RequestTicket
4	GetPID	GetPID
5	GetName	GetName
6	LoginWithContext	ValidateAndRequestTicketWithParam

Usernames are not case sensitive.

If the username does not exist, the %retval% field is set to RendezVous::InvalidUsername and the other fields are left blank.

Type	Name	Description
String	strUserName	Username

Type	Name	Description
Result	%retval%	Result code
PID	pidPrincipal	User pid
Buffer	pbufResponse	Kerberos ticket
RVConnectionData	pConnectionData	Connection info for secure server. The Nintendo Switch allows the secure server to be at the same address as the authentication server. In that case, the secure server station url points to 0.0.0.1 with port 1.
String	strReturnMsg	Server build name

Examples of server build names:

Server	Build name
Friends	branch:origin/feature/45925_FixAutoReconnect build:3_10_11_2006_0
DKC:TF	branch:origin/release/ngs/3.4.x.3 build:3_4_13_3_0
MK8	branch:origin/project/wup-amk build:3_5_17_2011_0

Usernames are not case sensitive.

If the username does not exist, the %retval% field is set to RendezVous::InvalidUsername and the other fields are left blank.

Wii U servers don't seem to check what's in the extra data.

Type	Name	Description
String	strUserName	Username
Any<AuthenticationInfo>	oExtraData	Authentication info

This structure inherits from Data

Type	Name	Description
String	m_authToken	Token, as received from the account server
Uint32	m_ngsVersion	Always 3 on Wii U. Always 4 on Switch.
Uint8	m_authTokenType	Always 1 on Wii U. Always 2 on Switch.
Uint32	m_serverVersion	See below

The server version is in the build name of the server. If the build name is 3_x_y_z_0 then z is the server version. Click here for a list of server build names.

Type	Name	Description
Result	%retval%	Result code
PID	pidPrincipal	User pid
Buffer	pbufResponse	Kerberos ticket
RVConnectionData	pConnectionData	Connection info for secure server. The Nintendo Switch allows the secure server to be at the same address as the authentication server. In that case, the secure server station url points to 0.0.0.1 with port 1.
String	strReturnMsg	Server build name
String	pSourceKey	Only present on Switch. If this is a non-empty hex string, key derivation is skipped and this string is used as the key to decrypt the ticket instead.

If the source or target pid is invalid, the %retval% field is set to Core::AccessDenied and the ticket is empty.

Type	Name	Description
PID	idSource	User pid
PID	idTarget	Secure server pid

Result	%retval%	Result code
Buffer	bufResponse	Kerberos ticket
String	pSourceKey	Only present on Switch. If this is a non-empty hex string, key derivation is skipped and this string is used as the key to decrypt the ticket instead.

This is the reverse of the GetName method. It looks up the pid that belongs to a given username. On all normal accounts the username is the same as the user pid. Each game server also provides a bunch of special users.

Usernames are not case sensitive.

Returns 0 if the username does not exist.

Type	Name	Description
String	strUserName	Username

Type	Name	Description
PID	%retval%	PID

This is the reverse of the GetPID method. It returns the name associated with the given user pid. Returns an empty string if the pid does not exist.

Type	Name	Description
Any	loginData	Login data

Uint32	platformType	Always 3
String	userName	Username (your pid)
Any	extraData	NullData or AuthenticationInfo
Bool	ignoreApiVersionCheck
Uint32	apiVersionGeneral	NEX version (e.g. 40601)
Uint32	apiVersionCustom	Client version
