Hi,
the complementary auxiliary basis (cabs) sets are stored in the directory cabasen. There is no cabs optimized for def2-TZVP for sulfur. However, cabs are available for the cc or Dunning basis sets such as aug-cc-pVTZ etc., these were downloaded from K.A. Peterson's homepage on July 27, 2009. So, you could also check Peterson's homepage for updates.
Best regards
