[Samba] Problems with the Perl scripts smbldap-tools

[Jim]

I can't get the Perl script that is commonly used in the 'add user 
script' line to work (smbldap-useradd.pl).  It works fine from the 
command line but when I try to join a domain it will not add the new 
computer.  If I add the computer manually I have no trouble joining the 
domain.

I've tried both of the following lines:

add user script = /usr/bin/smbldap-useradd.pl -w -d /dev/null -g 
Machines -c 'Machine Account' -s /bin/false %u

add user script = /usr/bin/smbldap-useradd.pl -w -d /dev/null -g 
Machines -s /bin/false %u

Note that /usr/bin/smbldap-useradd.pl is a link.

This must be a common problem.  Can anyone enlighten me in regards to 
who the usual suspects are?
