Hmm ... I should say that my knowledge of the FTS is limited, but after a quick look at this I think the basic problem is that the way the FTS treats proxy renewal has changed and the documentation hasn't caught up, probably because the FTS developers are assuming that only the LHC experiments use it and it's only experts who need to know about it because it's buried inside their frameworks. I think that FTS now manages proxies in a similar way to the WMS, with an internal service that manages renewal, and the method with myproxy passwords only works with SEs which don't require VOMS attributes. I would suggest that someone submits a GGUS ticket asking for precise instructions on how to submit FTS transfers in such a way that VOMS credentials get renewed and presented to the SE.
