ok, I found a little issue with parameters (it seems the second -debug was overriding all the rest).
Now I get exactly as in Wei's case:

the difference here is that the File::Open is NOT blocked by the FS and hence it still works …

so even if the log says


130208 10:49:07 30219 secgsiVOMS_Fun: VOMS extensions do not match required criteria (grpopt=0;grps=/cms;vos=cms)

it still goes on..
