Hi.

Try --force-badname option in useradd

When I try to add them manually using "/usr/sbin/useradd -g machines -d /dev/null -c "Spruce" -s /bin/false SPRUCE$", I get the error message: "invalid user name 'SPRUCE$'".  I can add the user without the dollar sign, then go in and edit /etc/passwd and /etc/shadow and add the dollar sign, but this process is kind of tedious.  I have tried the "add machine script = /usr/sbin/useradd -d /dev/null -g machines -s /bin/false -M %u" line in smb.conf, but that doesn't work.  I get an error message when I try to join the domain (I forget what the error is, sorry).  I think the problem is due to useradd not accepting dollar signs at the end of machine names.  Can anybody think of a way around this?  Is there a way I can use a different version of useradd that will accept dollar signs?
