title: Azure Multi-Factor Authentication Server log in Failures
body: <p>I have installed an Azure MFA on our network to provide two form Id for our VPN. We are using the Azure MFA pay as you go option where users are added and charged as we add them to the server.</p>
  
  <p>I have import the users from AD.  Ninety  percent of the users imported  work file.  I have both enabled an not enabled users  listed on the server.  </p>
  
  <p>When I run a test from within the MFA server the authentication process works.  The server will call the number I have listed and when I press the # key to accept the system returns that that use authenticated  ok.</p>
  
  <p>The ones I am have problems with will  authenticate with I use the test button on MFA server, but when I try to use the same user to login to the VPN
  I get this error</p>
  
  <p>Pfauth failed for user 'CN=test@xxxx.com,CN=Users,DC=xxxx,DC=com' (distinguishedName format) from xxx.xxx.xxx.xxx.  Call status: SKIPPED_NO_USER - "Couldn't match supplied username to a defined user".</p>
  
  <p>Other users have no problem logging in. </p>
  
  <p>I have tried to re-import the user, recreate the use manual in the MFA server nothing changes the results. </p>
  
  <p>It looks to me that the error is that the MFA server does not recognize the server.  Has anyone seen this problem or can direct me to thing to check.</p>
