Hello, i have a problem with the samba profiles binary. I want to change the sid from some XP user profiles (ntuser.dat) to migrate them from NT4 to Samba3. Everytime i run the profile tool, i got an error. I'm using Debian Sarge and the profil tool from samba 3.0.25a. Here is the output from gdb: (gdb) file:~# gdb ./profiles GNU gdb 6.3-debian Copyright 2004 Free Software Foundation, Inc.
