<p>This function uses the credentials <em>creds</em> to set the password <em>newpw</em> for the principal <em>change_password_for</em> . It implements the set password operation of RFC 3244, for interoperability with Microsoft Windows implementations.</p>
<p>The error code and strings are returned in <em>result_code</em> , <em>result_code_string</em> and <em>result_string</em> .</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>If <em>change_password_for</em> is NULL, the change is performed on the current principal. If <em>change_password_for</em> is non-null, the change is performed on the principal name passed in <em>change_password_for</em> .</p>
