username map问题

smb.conf 文件如下
[global]


             workgroup = workgroup
             server string = xiao xiong server %v
        security = user
        
         username map = /etc/samba/smbusers
smb passwd file = /etc/samba/smbpasswd
;       passdb backend = tdbsam
        load printers = yes
        cups options = raw
[sales]
                  comment = sales data
path = /companydata/sales
valid users =@xiong
[sales2]
                         comment =sales2 data
path = /companydata/sale2
valid user =sale2

smbusers 文件如下
# Unix_name = SMB_name1 SMB_name2 ...
root = admin administrator
nobody = guest pcguest smbguest
lcf = laicarfore lai
yu = laicarfore


yu SMB帐可以登陆，可是laicarfore一直登不了！，请问一下怎么回事，菜鸟等

lcf能登吗？
