  <adm:synopsis>
    The
    <adm:user-friendly-name />
    determines whether a proposed password is acceptable by measuring 
    how similar it is to the user's current password. 
  </adm:synopsis>
  <adm:description>  
    In particular, 
    it uses the Levenshtein Distance algorithm to determine the 
    minimum number of changes (where a change may be inserting, 
    deleting, or replacing a character) to transform one string into 
    the other. It can be used to prevent users from making only minor 
    changes to their current password when setting a new password. 
    Note that for this password validator to be effective, it is 
    necessary to have access to the user's current password. 
    Therefore, if this password validator is to be enabled, the 
    password-change-requires-current-password attribute in the 
    password policy configuration must also be set to true.
