[Samba] using smbpasswd noninteractively?

[paul k]

hi folks,

I'd like to use smbpasswd without getting promted for the pw, there is 
the -s switch making smbpasswd read from stdin but it still wants to 
have the pw twice and two "returns". I tried  feeding it with "passwd \r 
passwd \r" and calling smbpasswd from python using os.popen2() and 
writing to the "stdin" file object but everything failed so far.

any ideas?

thx
   Paul
