RE: Unable to mount using credentials file

["Roger Brooks" <r.s.brooks-EkmVulN54Sk@public.gmane.org>]

P.S.
There was a non-printing character in the directory name under /root.
After correcting that, mount.cifs -o credentials=<filename> works.
However, mount -t cifs -o credentials=<filename> still returns "Invalid argument".
Can I just use mount.cifs directly, or does mount perform some additional needed housekeeping?
If mount is needed, how can I get -o credentials to work?
TIA for any tips!

Hi Benjamin,

Thanks for responding.

The credentials file is a simple text file created with vi containing the lines:
>>
username=<user>
password=<password>
<<
I have tried this both with and without trailing newline at the end of the second line.

I have also tried the variant:
>>
username=<user>
password=<password>
domain=<domain>
<<

The results are always the same.
If there is a problem with the *content* of the file, why would the error message say that the file could not be opened?

Thanks for your help!
Best Regards,
Roger

Hi,
Does your credential file is correctly formatted ?

2014-11-01 13:03 GMT+01:00 Roger Brooks <r.s.brooks-EkmVulN54Sk@public.gmane.org>:
I am attempting to mount Windows volumes on a Synology DS (running DSM 5.0, a Debian-based distribution).
Command lines of the form:
mount -t cifs -o username=<user>,password=<pass> //<IP address>/share/ /mnt/<mountpoint> succeed.
However, command lines of the form:
mount -t cifs -o credentials=<filename> //<IP address>/share/ /mnt/<mountpoint> fail with the error "Invalid argument".
For diagnostic purposes, I have attempted to mount the volumes directly using mount.cifs (v5.5).
Once again, commands of the form:
mount.cifs //<IP address>/<share> /mnt/<mountpoint>/ -o username=<user>,password=<password>
succeed.
However, commands of the form:
mount.cifs //<IP address>/<share> /mnt/<mountpoint>/ -o credentials=<file> fail with the error message:
error -1 (Unknown error 4294967295) opening credential file <file> This is the case regardless of the location of the file (see
http://samba.2283325.n4.nabble.com/Error-s-opening-credentials-file-td2518214.html)
or its privileges.  The error persists, even when the command is executed from a root session and the credentials file has permissions 0777 and is in a subdirectory of /root.
How can I get mount to work using a credentials file?
