[Samba] user not in group

[Samba Guy]

I used smbgroupedit and it makes the mappings, but I still get:

[2002/12/02 12:28:13, 2] auth/auth.c:check_ntlm_password(261)
  check_password:  authentication for user [test1] -> [test1] -> [test1]
suceeded
[2002/12/02 12:28:13, 0] rpc_server/srv_util.c:get_domain_user_groups(342)
  get_domain_user_groups: primary gid of user [test1] is not a Domain
group !
  get_domain_user_groups: You should fix it, NT doesn't like that
