I have a debian server with samba. I can no longer manage users accounts. I can't add, modify or remove them.
This is Debian wheezy with samba 3.6.6. There is no ldap and the database backend is tdb. I usually managed users with smbpasswd, but it no longer works.
When I try to create a new user:
smbpasswd -a blabla New SMB password: **** Retype new SMB password: **** Failed to add entry for user blabla.
Trying to remove users with pdbedit or smbpasswd isn't working also, returning the same error:
# pdbedit -L olduser olduser:1314:OldName # smbpasswd -x olduser Failed to delete entry for user olduser.
I tried using tdbtool
# tdbtool /var/lib/samba/passdb.tdb check Database integrity is OK and has 570 records.
I checked the keys length, I made a tiny perl script that checked all the output of tdbtool keys to see if one entry had different keys thant it should, but I see no mistakes there:
key 9 bytes: USER_old
I'm stuck, any hint would be appreciated, thank you.
