I have a somewhat odd setup here and am having a permissions
problem with my userid and authentication.
In general I'm trying to have one home directory that is shared
between Windows and Linux. On Windows I use Cygwin. Normally this
involves mounting my Windows oriented home directory and proper
generation of my domain userid in /etc/passwd. Here things are a
bit different.
My home directory here is on a Linux box running Samba. I login as
<domain>\defaria on my Windows box. I have generated my
/etc/password entry with mkpasswd -d -u defaria > /etc/passwd.
However the Linux box running Samba does not participate in a
domain rather it is using
a workgroup.
I don't have access to a Samba mount point, so maybe my advice won't
help much, but here goes anyways.
The symptoms that I see are as follows:
While I can create a file in my home directory I cannot edit it -
access denied:
$ cp opts.cfg opts.cfg.new
cp: cannot create regular file `opts.cfg.new': Permission denied
$ ls -l opts.cfg*
-rw-rw-r-- 1 ???????? ???????? 98 Feb 14 11:17 opts.cfg
-rwxr--r-- 1 ???????? ???????? 0 Feb 15 16:01 opts.cfg.new*
You'll note that the uid and gid is not correct.
First, have you run mkpasswd and mkgroup to create valid /etc/passwd
and /etc/group files? Without a valid user database, cygwin gets lost
when trying to check/display/modify permissions of an unknown user.
http://cygwin.com/cygwin-ug-net/using-utils.html#mkpasswd has more
details on running mkpasswd.
I've run mkpasswd but the real question I believe is what domain should
I run mkpasswd for? As I stated above I have run it for the Windows
domain that I log into. However, again, my home directory is served by a
Linux box using Samba but that link box does not participate in the
Windows domain that I log into rather it just runs in it's own workgroup.
