cifs mount not working with uid option?

[Gianluca Cecchi]

Hello,
my system is an updated Fedora 25.
A previously working windows share mounted via cifs is not working now (I
have not the details of it but I know only that it is a DFS share, managed
by a cluster of two windows 2012 R2 servers)
After some attempts, I have verified that the critical point seems to be
the "uid=1000" option that I previously used to map permission of files and
to be able to change them.

entry in fstab working
\\my.windows.domain\home\path1\path2\path3 /myshare              cifs
 noauto,_netdev,credentials=/etc/smbcred_myshare  0 0

entry in fstab not working (verified the same from command line, doubling
the slashes in this case)
\\my.windows.domain\home\path1\path2\path3 /myshare              cifs
 noauto,_netdev,forceuid,uid=1000,credentials=/etc/smbcred_myshare  0 0

NOTE: I tried both with and without the forceuid option when using the uid=
one but no go in both.

Of course my linux username is not the same as the username used in
credential file.
If I mount without uid I get all files owned by root and not able to modify
anything in Linux.
Any hint on what to try?

Thanks in advance,
Gianluca

I forgot to say that using the uid option I get this kind of message:

# mount /asishare/
mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
#

But no mount takes place...

I am using CIFS to mount a windows share on a NAS
device attached to my 
router, but I am not using the uid option, instead I am using the user= 
and password= options to specify the userid and password that I have 
defined on my NAS device. The userid and password also happen to match 
my Linux userid and password. With these options I have write access 
from Linux and Windows can see the files also. Before adding these two 
options I was getting the same issue you are reporting, of Root being 
the owner, but Windows had no issues, even though I had specified 
internally in the device that it was public. Why do you need the uid 
option when you are supplying a credentials file, I would have assumed 
the credentials file would be specifying the information that would give 
your Linux userid the required access?
Also, if the device you are mounting is on a remote server, could your 
issue be that the server no longer gives the users listed in your 
credentials file access to the path you are trying to mount?

Steve
