--- Comment #21 from Alois Steindl <alois.stei...@tuwien.ac.at> --- I already have samba 4.7.7 installed (Fedora 27) and the behaviour is still the same. (In the meantime also an updated Scientific Linux 7.5 version, which behaved fine originally, shows this behaviour.) I played also around with 4.8.0 and couldn't find a difference. If I set "client max protocol = NT1" in ~/.smb/smb.conf, the problem vanishes. I also tried to run the test programs in the samba distributions, they didn't show that problem. As the problem now seems to be related with file permissions, a maybe very simple remark/question: If I call smbtree, the program displays the available workgroup and connected machines properly, without asking for any credentials. Shouldn't clicking on "Samba Shares" in dolphin or konqueror behave the same? The user should find a list of available shares, without immediate need to login. Of course, if I want to open a directory, the password dialog should be opened. I do not know the internal flow of these programs sufficiently well - and didn't succeed to find that out by running the test programs and looking at the sources -, but it seems to me, that the EPERM error shouldn't be returned yet. Actually the error doesn't cause any problems, because I need only connect to a few addresses, for which I can provide the full samba URL in the list of network shares. But a possible exception with signal 11 might cause security problems. With best wishes Alois -- You are receiving this mail because: You are watching all bug changes.
