I tried to mount a cifs-share (Host Solaris/OmniOS actual version, ReadX-ACL, read&execute).
Command: mount -t cifs -o username=xx,password=xx,sec=ntlm,ro //server/share /mountpoint
Version mount.cifs 5.5
After that, I can browse the directories and list the files, but it is impossible to access the files (open or copy). It aborts with "permission denied" error in reading file.
When using credentials with "Full Access" everything works fine.
Using the Read-Only credentials with windows 7 client - I can access the files, open and copy it.
So I think, it is an issue with mount.cifs.
I reproduced it with actual debian linux, Raspbmc, Openelec.
Thanks a lot for your help
