    • convertObjectGUIDToByteString

      public static String convertObjectGUIDToByteString(byte[] objectGUID)

      Creates a byte-based String representation of a raw byte array representing the value of the objectGUID attribute retrieved from Active Directory.

      The returned string is useful to perform queries on AD based on the objectGUID value. Eg.:

      String filter = "(&(objectClass=*)(objectGUID" + EQUAL + convertObjectGUIDToByteString(objectGUID) + "))";

      Parameters:
      objectGUID - A raw byte array representing the value of the objectGUID attribute retrieved from Active Directory.
      Returns:
      A byte-based String representation in the form of \[0]\[1]\[2]\[3]\[4]\[5]\[6]\[7]\[8]\[9]\[10]\[11]\[12]\[13]\[14]\[15]

      public static String convertGUIDToEdirectoryHexString(String guid)
      see http://support.novell.com/docs/Tids/Solutions/10096551.html
      Parameters:
      guid - A GUID in the form of a dashed String as the result of (@see LDAPUtil#convertToDashedString)
      Returns:
      A String representation in the form of \[0][1]\[2][3]\[4][5]\[6][7]\[8][9]\[10][11]\[12][13]\[14][15]

      public static byte[] encodeObjectEDirectoryGUID(String guid)
      Converts the EDirectory GUID string into the byte array.
      Parameters:
      guid -
      Returns:

    • encodeObjectGUID

      public static byte[] encodeObjectGUID(String displayString)

      Encode a string representing the display value of the objectGUID attribute retrieved from Active Directory.

      Parameters:
      displayString - A string representing the decoded value in the form of [3][2][1][0]-[5][4]-[7][6]-[8][9]-[10][11][12][13][14][15].
      Returns:
      A raw byte array representing the value of the objectGUID attribute retrieved from Active Directory.

    • decodeObjectGUID

      public static String decodeObjectGUID(byte[] objectGUID)

      Decode a raw byte array representing the value of the objectGUID attribute retrieved from Active Directory.

      The returned string is useful to directly bind an entry. Eg.:

      String bindingString = decodeObjectGUID(objectGUID);
      Attributes attributes = ctx.getAttributes(bindingString);

      Parameters:
      objectGUID - A raw byte array representing the value of the objectGUID attribute retrieved from Active Directory.
      Returns:
      A string representing the decoded value in the form of [3][2][1][0]-[5][4]-[7][6]-[8][9]-[10][11][12][13][14][15].
