Cygwin gurus,
Frustrated by permission problems resulting from having two accounts
with the same user name (one domain, one local) I decided to start over
with my cygwin installation. This time, I logged in as local
administrator (account name say admin AT local) and installed cygwin as
this user. Then, to make sure I could read and use cygwin from my
domain account I used the Windows ACLs to also grant my domain account
"Full Control" to all the files in C:\cygwin. Thus, both my admin AT local
(local admin) and my admin AT domain (domain admin) have Full Control to
files in C:\cygwin. But, while logged in both as admin AT local and as
admin AT domain I tried from Windows Explorer to delete a file and was
informed that I do not have permission! So, I launched the cygwin bash
window (from admin AT local) and performed a chmod 777 on the file (which
cygwin allowed) and STILL can't delete the file:
admin AT local /usr/bin
$ ls -la rsync.exe
-rwxrwxrwx 1 senior Users 245248 Aug 18 03:56 rsync.exe
admin AT local /usr/bin
$ rm -f rsync.exe
rm: cannot remove `rsync.exe': Permission denied
admin AT local /usr/bin
$
I have read the documentation on NTSEC and from my limited understanding
of it was able to glean that using the Windows ACLs was probably not the
right way to grant access to the admin AT domain account. What is the best
way to allow access of cygwin to *all* administrators and can I repair
this permissions on this installation? Thanks again.
