I followed this guide: http://www.lancs.ac.uk/iss/tsg/unix-ad/ to configure a Ubuntu 12.04.02 Client to authenticate on Active Directory (on a Windows 2008R2 Server), i did everything step by step but I'm not able to see any remote users.

This are my config files:

Code:
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
