  I'm quite new to the Samba world, so may be my
question was stupid or difficult to understand or whatever.
Another try - the question is:

Can I use any Samba tool to:
- bind to an NT PDC as administrator
- set the password of another user to a new value (without
  knowing the old value)

In LDAP terms (this is the topic I know ...) it would be:

ldapmodify -D "cn=administrator,dc=company,dc=com" -w secret
-h pdc_host -p 389
dn: uid=123,dc=company,dc=com
changetype: modify
replace: userPassword
userPassword: newpassword

Any hint is appreciated.
Thanks,  Jochen.
