Hi,
Yes, I wanted this (in BaBar) to be the site-wide KanAccess config file
rather than in user .rootrc files. I forget the syntax, but there was some
line to pass something through to the ROOT environment. (The primary reason
is that once it gets into user .rootrc files, you'll never get it back
out...)
I think this is fixed in the version of XTNetFile in analysis-22 (again
in BaBar) and the problem was also fixed before the integration of XTNetFile
as TXNetFile into ROOT itself. So it is only relevant for people using
analysis-21 or earlier in BaBar. [And they IMO should (very soon) be pushed
forward to analysis-22 (_and_ SL3). I don't understand why a RH72 version of
analysis-22 was made.]

I'm away from 8 Oct - 4 Nov (inclusive) with only occasional access
to email, so you should expect some delay in my responses.
