Hello I took a look at the drive properties ones more. The following acl rights has been given me by the network administrator: - change file permission: no - all others: yes
Unfortunately the Windows has a special attribute 'write protection' which can be set in the mask for file's attribute. So there is a kind of conflict now. Despite I can't change file permissions (in the acl) I can every time set/reset the bit 'write protection'. I see, it is very interesting feature of the so called operating system. There is the question at this place: Should the implementation of chmod allow the setting/resetting of the 'write protection' bit in spite of the missing permission 'change file permission' in the acl ?

Yes. Opening the file fails with "access denied" and then chmod has no file handle to work with. I'm sorry but I tried with 1.5.15 and 1.5.16 and I couldn't find a situation in which this happens for me.
