[Samba] smbadduser error

[Leonardo Rodríguez]

Hi List,

I have a problem authenticanting some of the users into a Windows 2000 PDC
with Samba 2.2.5.
The thing is that I can add some of the users in the PDC as Samba users but
with some of them I can't, I run the following command and I get this:

# smbadduser lrodrigu:lrodrigu
ERROR: lrodrigu Not in passwd database SKIPPING...
#

But the user 'lrodrigu' is in the passwd database (/etc/passwd) so I don't
get it.
However, some of the users aren't in that file and I can add them as Samba
users...
It's weird, isn't it?

Well, Here you are the users in the DOMAIN:

# wbinfo -u
Administrator
db2admin
Guest
guigonza
IUSR_HAL
IWAM_HAL
krbtgt
leosamba
lrodrigu
NetShowServices
nuevo
pruebasamba
samba
smbusr
sysadm
TsInternetUser
usrsamba
#

If anybody knows how to fix this problem or has any clue about it, please
let it me know...

Thanks in advance

Leonardo
