<p>Client considers EXTERNAL to be its preferred SASL mechanism so it attempts to complete SASL negotiation using that mechanism. The following paragraphs illustrate several possible paths, depending on whether the client includes an authorization identity (for the official rules regarding when to include the authorization identity, see Section 6.3.8 of <cite>RFC 6120</cite>).</p>

<p>Server1 considers EXTERNAL to be its preferred SASL mechanism. Here it includes a base-64-encoded authorization identity as the XML character data of the &lt;auth/&gt; element, setting it to the same value as the 'from' address on the stream header it sent to Server2.</p>
<p>Server1 considers EXTERNAL to be its preferred SASL mechanism. For server-to-server authentication the &lt;auth/&gt; element MUST NOT include an authorization identity (thus Server1 includes an empty response of "=" as shown in <cite>RFC 6120</cite>).</p>

<p>(In this case, the authorization identity is "conference.example.org".)</p>
<p>Interoperability Note: Previous versions of this specification relied on the authorization identity being present on the receiving server. Even though this is no longer required, the connecting server should include it for backward compability.</p>

<p>If the 'from' attribute of stream header sent by Server1 can be matched against one of the identifiers provided in the certificate following the matching rules from <cite>RFC 6125</cite>, Server2 returns success.</p>

<p>Implementation Note: If Server2 needs to assign an authorization identity during SASL negotiation, it SHOULD use the value of the 'from' attribute of the stream header sent by Server1.</p>
