#30 Unable to perform operations on users with $ char in the nam

[Fabian Groffen]

I tried using cpu to manage my LDAP with samba accounts
in it. I know samba can do LDAP itself, but for some
historical legacy reasons my current setup just doesn't
use LDAP itself. So I replaced in the machine add
script /usr/sbin/useradd with cpu useradd to let samba
add machine accounts to the LDAP server.

This, however, does not work as samba adds an $ to the
end of machine account user names. This way I cannot
remove such accounts using cpu as well. If I remove
the $ in a manual test all works well. As soon as
there is a $ in the login cpu acts as if it was not
given at all. I think this is incorrect, as the
original useradd unix tool is able to add such user.

example output:
# /usr/sbin/cpu useradd -d /dev/null -g machines -c
'Machine Account' -s /bin/false test_machine
User test_machine successfully added!
# /usr/sbin/cpu useradd -d /dev/null -g machines -c
'Machine Account' -s /bin/false test_machine$

Idem with spaces or @... LDAP supports it, but CPU not.
