Error adding new user to samba pdc


Hi there!
i'm running Etch with samba 3.2.3.
I have here a samba pdc, which worked just fine until some days ago. The problem is that I can't add anymore users to the samba database!! i can still remove users or modify passwords.
here what I get
Code:
servidor:/var/lib/samba# smbpasswd -a lorenzo
New SMB password:
Retype new SMB password:
Unable to modify TDB passwd: NT_STATUS_UNSUCCESSFUL!
Failed to add entry for user lorenzo.
Failed to modify password entry for user lorenzo
This NT_STATUS_UNSUCCESSFUL error seems a generic error from samba, which returned tons of web pages about lots of different errors. If I try to set the debug lvl to 10, i get a "pdb_getsampwnam (TDB): error fetching database.".

Code:
servidor:/var/lib/samba# smbpasswd -D 10 -a lorenzo
Netbios name list:-
my_netbios_names[0]="SERVIDOR"

I googled without success and even looked at the source code. it seemed to me that there's some kind of corruption in my passdb.tdb file.
does anyone know what i can do to solve this problem?
if not, how can I reset the db? just by rm *.tdb?
i'll be very upset to re-add all the machines and users to the domain

thanks for any help and for your time

Try removing lorenzo from the database:
Code:
smbpasswd -x lorenzo
and then re-adding him. Perhaps that will fix things? I had similar (but not exactly) issue when I tried to add a user that I had added before. Somehow there was something left behind that I was un-aware of and it caused problems. I eventually removed the user from samba and then the machine and tried it again.

Thks for replying.
I tried doing so, but unfortunately without success, i get the same error:
Code:
servidor:/home/alisson# smbpasswd -x lorenzo
Failed to delete entry for user lorenzo.
Failed to modify password entry for user lorenzo
servidor:/home/alisson# smbpasswd -a lorenzo
New SMB password:
Retype new SMB password:
