    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:

    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 17.04:
      slapd                           2.4.44+dfsg-3ubuntu2.1
    
    Ubuntu 16.10:
      slapd                           2.4.42+dfsg-2ubuntu4.1
    
    Ubuntu 16.04 LTS:

      slapd                           2.4.31-1+nmu2ubuntu8.4
