ls -l /mnt/music
drwxrwx---   4 music users 128 30. Jan 2005  My Insanity


client:
mount //ipaddress/music /mnt/music -t cifs -o rw

  my local user is in the group users
  ls -l  /mnt/music
  drwxrwx---   4 1001 users 0 30. Jan 2005  My Insanity
  cd /mnt/music/My\ Insanity  <- works
  ls -l
  ls: dir .: no permission               (ls: lese Verzeichnis .: Keine
Berechtigung)


maybe it has something todo with the guest account, but i couldnt figure
that out.
basically i would like to mount a smb share over the network with my
local user whos is in group guest.
thx for any replys.
