Samba: Could not get smbpasswd to work. Problem?

[Dan Thurman]

Folks,

Trying to get my Samba server running on FC5, but cannot seem
to be able to get shares working right.  I noticed that I had
no entries in the /etc/samba/smbpasswd file so I tried to add
my users via smbpasswd <user> and provided the passwords but
smbpasswd failed to complete.  Here is the results:

[root at mysystem samba]# smbpasswd aUser
New SMB password:
Retype new SMB password:
Failed to find entry for user aUser.
Failed to modify password entry for user aUser

I checked to make sure that this user had an account
in the /etc/password file and yes, they do so I am not
sure why smbpasswd is not accepting it.

Anyone have problems with this?

Kind regards,
Dan
