title: WCF logging using Logging Application Block
body: <p>I have a WCF service which is secured with username and password (using SqlMembershipProvider). I'd like to log EVERY (succeeded and failed) login attempt to this service and save user credentials to the database using Logging Application Block. When I turn on WCF logging and trace it with Logging Application Block, i get something like this (about 100 of this logs for one login attempt):</p>

  <p>I cannot find any useful information from this logs (namely user credentials). So, my question is: how can i log user credentials from WCF services to the database using Logging Application Block?</p>
  
  <p>Thanks in advance for your answer!</p>
