samba - Nov 1999 - Failed logon to Samba PDC

Good morning, I have problem with logon to Samba 
2.0.5a (Debian 2.0.36).
Samba is setting like PDC, I have created account carrot 
in smbpasswd. Logon doesn't work, in log file is following
 message:

[1999/11/02 14:46:42, 0] smbd/uid.c:become_gid(105)
  Couldn't set effective gid to 1003 currently set to 
(real=0,eff=0)
[1999/11/02 14:46:42, 0] 
smbd/service.c:make_connection(463)
  Can't become connected user!
--
 Important part of smb.conf:
[global]

workgroup = vegetable
security = user
encrypt passwords = yes
domain logons = yes

os level = 65
domain master = yes
local master = yes
preffered master = yes

[netlogon]
path = /data/netlogon

Can you me consult, wherein is problem ? Bear it 
somehow with access right to smbpasswd ? 

thanks

Do you have this account in the Debian system as well?
I mean, in Debian's /etc/passwd or /etc/shadow? The same for the group.
