## Authentication

Sample Values:

* User: JohnDoe
* Domain: CONTOSO
* Password: Password123!
* Server: rdp.contoso.com

There simplest, unambiguous way of passing credentials at the command-line is with /u, /d and /p. The domain name is only needed if you connect using domain credentials:

xfreerdp /u:JohnDoe /d:CONTOSO /p:Password123! /v:rdp.contoso.com

The domain name can also be passed in the username using the same notation accepted by mstsc:

xfreerdp /u:CONTOSO\JohnDoe /p:Password123! /v:rdp.contoso.com

While the above notation is shorter, it has an unpractical side effect: the backslash is often, but not always, interpreted as an escape character. To avoid the problem, make sure the shell does not interpret the backslash as an escape character:

xfreerdp /u:CONTOSO\\JohnDoe /p:Password123! /v:rdp.contoso.com
xfreerdp "/u:CONTOSO\JohnDoe" /p:Password123! /v:rdp.contoso.com

From experience, most Linux shells will require such handling of the backslash character. However, there are certain cases like the Eclipse launcher which do not require it.

Alternatively, the User Principal Name (UPN) notation can be used:

xfreerdp /u:JohnDoe@CONTOSO /p:Password123! /v:rdp.contoso.com

This notation does not have the drawbacks of the backslash character, but introduces a potential conflict with usernames containing the '@' symbol and no domain name. This is frequently the case with the new Windows 8 Microsoft Accounts (a.k.a. Windows Live Accounts) which correspond to an email address. To work work around the ambiguity, precede the user name "john.doe@live.com" with a backslash:

xfreerdp /u:\john.doe@live.com /p:Password123! /v:rdp.contoso.com

Be careful to properly handle the backslash character as previously instructed.

Passwords entered as command-line arguments could potentially be seen by other users on the same system, so they are automatically hidden:

awake@workstation:~$ ps aux | grep freerdp
awake 22506 0.0 0.1 2502620 10236 s002 S+ 11:10pm 0:01.00 xfreerdp /u:JohnDoe /p:************ /d:CONTOSO /v:rdp.contoso.com

### Credentials Prompt

If you omit entering credentials at the command-line, FreeRDP may prompt you for credentials depending on the negotiated protocol security level.

#### Protocol Security

RDP protocol security is confusing for many users because it strongly affects the way credentials can be prompted. There are three main security levels that can be negotiated:

* RDP Security (old encryption, old authentication)
* TLS Security (TLS encryption, old authentication)
* NLA Security (TLS encryption, NLA authentication)

##### Old Authentication

The old RDP authentication mechanism is very simple: the server presents the client with the Winlogon GUI, and the user can either automatically or manually enter the credentials. If you enter credentials prior to connecting to a server with the old authentication, they will be automatically on connection, saving you the trouble of typing them manually.

Old RDP authentication may be practical in the sense that you can get a remote Winlogon GUI without being authenticated on the server. This is however a design flaw which makes the RDP server vulnerable to a DDOS attack: since significant resources need to be allocated for the Winlogon GUI without being authenticated, a distributed denial of service attack could be performed by simply launching multiple unauthenticated connections. This is exactly why it is no longer possible to obtain such a GUI prior to authentication with newer security levels.

##### Network Level Authentication (NLA)

Network Level Authentication (NLA) is required by default with servers starting with Windows Vista. With NLA, authentication is the very first thing that occurs over the wire, such that the server will only allocate resources and present a graphical interface to authenticated clients. It is also much more secure and provides strong defense mechanisms against Man-in-the-Middle (MITM) attacks.

When NLA is negotiated, the complete credentials are needed at connection time, which is why FreeRDP will prompt for the missing information:

xfreerdp /u:JohnDoe /d:CONTOSO /v:rdp.contoso.com
connected to rdp.contoso.com
