I don't mean to nag... but I must get this problem fixed soon..... and it seems to be a common one on these mailing lists... I cannot add my Win2K Sp3 machine to my samba PDC... i receive the error message "No mapping between account names and securityids was done" I have created the machine account... the machine account and root are added in smbpasswd.... I have checked and they DO exist... I am running Samba 2.2.6-1, the build which many on these lists claim to fix this win2k problem.... but as of yet... no luck... here is my smb.conf if anyone can find a problem in it # Samba config file created using SWAT # from duar (127.0.0.1) # Date: 2002/11/16 11:58:30 # Global parameters [global] workgroup = KRONOS netbios name = DUAR netbios aliases = DUAR server string encrypt passwords = Yes update encrypted = Yes pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n *passwd:*all*authentication*tokens*updated*successfully* passwd chat debug = Yes username map = /etc/samba/smbusers unix password sync = Yes admin log = Yes log file = /var/log/samba/log.%m max log size = 50 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 domain admin group = @DomainAdmins domain guest group = @DomainGuests domain logons = Yes os level = 33 lm announce = Yes preferred master = Yes domain master = Yes dns proxy = No winbind use default domain = Yes alternate permissions = Yes valid users = root admin users = root printer admin = root printing = lprng [homes] comment = Home Directories valid users = %S read only = No create mask = 0664 directory mask = 0775 browseable = No Yours Hopefully Steve Jackson
