Wrong. It has been fixed in the snapshot. 1.7.9 tries to open the file
with WRITE_DAC access which fails on some shares. The snapshots won't
do that anymore.

Good! That shows that my assumption is correct.

Then "noacl' is the only way for you.

Check with your admin and ask how they make sure that you can't set
permissions. Did they just create a certain set of inheritable
permissions or do they use some policy? That is what I'd like to know.
The answer, however, will only help me to understand, it will not help
you to avoid the "noacl" setting.
