title: input claim for extension_passwordResetOn always "undefined"
body: <p>I am trying to set up a custom B2C policy according to sample available at: <a href="https://github.com/azure-ad-b2c/samples/blob/master/policies/force-password-reset-after-90-days/policy/TrustFrameworkExtensions.xml" rel="nofollow noreferrer">https://github.com/azure-ad-b2c/samples/blob/master/policies/force-password-reset-after-90-days/policy/TrustFrameworkExtensions.xml</a></p>
  <p>The problem I face is that on every sign in pass change is prompted. I narrowed down the issue to
  InputClaim  isPasswordResetOnPresent always returned as false from where output claim &quot;skipPasswordReset&quot; is also FALSE every time</p>
  <p>and i believe this is my failing piece</p>
  <pre class="lang-xml prettyprint-override"><code>&lt;!--Sample: Check if extension_passwordResetOn is existed in user account. --&gt;
  &lt;ClaimsTransformation Id=&quot;CheckIfPasswordResetOnPresent&quot; TransformationMethod=&quot;DoesClaimExist&quot;&gt;
      &lt;InputClaims&gt;
        &lt;InputClaim ClaimTypeReferenceId=&quot;extension_passwordResetOn&quot; TransformationClaimType=&quot;inputClaim&quot; /&gt;
      &lt;/InputClaims&gt;
      &lt;OutputClaims&gt;
        &lt;OutputClaim ClaimTypeReferenceId=&quot;isPasswordResetOnPresent&quot; TransformationClaimType=&quot;outputClaim&quot; /&gt;
      &lt;/OutputClaims&gt;
  &lt;/ClaimsTransformation&gt;
  </code></pre>
  <p>This is evaluated in my Azure AD B2C trace as:</p>
  <pre><code>InputClaim  extension_passwordResetOn   undefined
  </code></pre>
  <p>I also followed all recommendations as per this similar question</p>
  <p><a href="https://stackoverflow.com/questions/63169671/azure-b2c-where-to-create-datetime-extension-attribute-to-be-used-in-custom-pol">Azure B2C: Where to Create DateTime Extension Attribute to be used in Custom Policy- Portal or Custom Policy or Both?</a></p>
  <p>But that extension_passwordResetOn is always determined as undefined in claims transformation
  In the same time I can see this extension get current date/time correctly assigned in this technical profile</p>
  <pre class="lang-xml prettyprint-override"><code>&lt;TechnicalProfile Id=&quot;AAD-UserWriteUsingLogonEmail&quot;&gt;
      &lt;InputClaimsTransformations&gt;
      &lt;!--Sample: Get current date and time --&gt;
          &lt;InputClaimsTransformation ReferenceId=&quot;SetPasswordResetOn&quot; /&gt;
      &lt;/InputClaimsTransformations&gt;
      &lt;PersistedClaims&gt;
          &lt;!--Sample: On sign-up, set the 'password reset on' extension attribute with the current date and time --&gt;
      &lt;PersistedClaim ClaimTypeReferenceId=&quot;extension_passwordResetOn&quot; /&gt;
      &lt;/PersistedClaims&gt;
  &lt;/TechnicalProfile&gt;
  </code></pre>
