Update your smbldap-tools to the latest version from www.idealx.org.
Samba-3.0.10 is NOT compatible with version 0.8.2 that is included with the
book. You should be using version 0.8.5.3. Also, with this version do not
include the '.pl' part of the filename in the smb.conf file. That has changed
since 0.8.2.

Do NOT include a service definition in your smb.conf file for [IPC$]. It is
not needed.

Please do NOT use the Idealx scripts that come with Samba 3.0.10 - please
obtain a fresh current version from Idealx.Org.

This has been discussed ad nauseum on this list. Suggest you go back over the
history of this discussion thread in the archives.

This is solved with the new Idealx smbldap-tool scripts.
