          FTS Configuration
          The current FTS tries SRM v1 unless endpoints are published correctly.
          To force type 2 use


          Once glite-data-transfer-agents 3_3_4_1 is released this will be default anyway.
          Given all sites are using SRM v2.2 now we recommend that this configuration be added to all the current FTSes now prior to this upgrade reaching production.

          The recommended baseline versions can be found here: https://twiki.cern.ch/twiki/bin/view/LCG/WLCGBaselineVersions
