Hi Samba List

I have the problem to modify an entry for a user in samba with tdb backend.

My OS is OpenSuSE 13.1, Samba 4.1.21. Samba NT'Style, no AD, no LDAP,
passdb backend = tdbsam

I managed to delete a User in my NIS/passwd File before I
deleted it in my Samba tdb. No the problem is, I can't modify the user
because he does not exists, but can not add, because he exists.

The problem seems to me related to the following mailing:

So I add the user in my NIS/passwd, but it does still not work.
