<p>You can use the UsernameToken to propagate a user name and, optionally, password information. Also, you can use this token type to carry basic authentication information. Both a user name and password are used to authenticate the message. A UsernameToken containing the user name is used in identity assertion, which establishes the identity of the user based on the trust relationship.</p>
|
||
|
|
|
||
|
|
<p>The following example shows the the syntax of the UsernameToken element:</p>
|
||
|
|
|
||
|
|
<pre><UsernameToken Id="...">
|
||
|
|
<Username>...</Username>
|
||
|
|
<Password Type="...">...</Password>
|
||
|
|
</UsernameToken></pre>
|
||
|
|
|
||
|
|
<p>The Web services security specification defines the following password types:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li><p><strong>wsse:PasswordText</strong>
|
||
|
|
<br>(Default) This type is the actual password for the user name. WebSphere Application Server - Express supports this type.</p></li>
|
||
|
|
|
||
|
|
<li><p><strong>wsse:PasswordDigest</strong>
|
||
|
|
<br>This type is the digest of the password for the user name. The value is a base64-encoded SHA1 hash value of the UTF8-encoded password. WebSphere Application Server - Express does not support password digest because most user registry security policies do not expose the password to the application software.</p></li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>The following example illustrates the use of the <UsernameToken> element:</p>
|
||
|
|
|
||
|
|
<pre><S:Envelope xmlns:S="http://www.w3.org/2001/12/soap-envelope"

|

|
|
<wsse:Username>Joe</wsse:Username>
|

|

|
<p>The password is transmitted in unencrypted text. Therefore, it is recommended that you use a secure transmission channel between the sender and receiver. For example, you might consider using Secure Sockets Layer (SSL).</p>
