samba - Oct 2012 - Added samba users do not appear, but maybe appear as groups.

Hi

I am a long term samba user and this is my first real problem.

Installation on Centos 5.8 originally Samba 3.033

It was on a server that had been crashing so about 8mths ago we put in a new
motherboard and the system seemed to be running OK, but we have not been adding
users or machines.

More recently the users wanted a new windows 7 machine and it would not let us
add the machine (The machine account does not exist)

We realized that we needed a later version of Samba and updated to Samba 3.5.17
(now 3.5.18)

The problem would not go away.

It seems that when we attempt to add a user account or a machine account, to the
smbpasswd file, it adds it to the file but not
to the user list when we do a wbinfo --domain-users

This means though we can add users to linux we can not add Samba users or
machine accounts.

I use webmin, this shows the users have not been added but if I look in the
samba groups they are listed.

They are not listed if I do a wbinfo --domain-groups

Can anyone shed a light of a fix for this as it is looking like a complete
server replacement, that is install on another machine and migrate.
