samba3入域后如何自动创建home目录？
系统是freebsd，已经安装了pam_mkhomedir插件，但好像不会自动建立文件夹啊？
我的配置文件：
[global]
    workgroup = abc
    netbios name = MY-SAMBA-SERVER
    wins server = ad.abc.com

    os level = 33

    security = domain
    encrypt passwords = yes
    password server = *

    allow trusted domains = No
    idmap config EXAMPLE:backend = rid
    idmap config EXAMPLE:range = 500-100000000
    idmap uid = 500-100000000
    idmap gid = 500-100000000
    template shell = /bin/sh
    winbind use default domain = Yes
    winbind enum users = No
    winbind enum groups = No
    winbind nested groups = Yes

[homes]
    comment = Home Directories
    browseable = no
    writeable = yes

[pub]
    comment = Public Stuff
    path = /var/ftp/pub
    valid users = @zixun
    write list = @zixun, @ftpuser

    vfs object = recycle
    recycle:repository = .recycle/%U
    recycle:keeptree = yes
    recycle:touch = yes
    recycle:versions = yes
    recycle:exclude = *.tmp, *.TMP

[backup]
    comment = Backup
    path = /backup
    valid users = @zixun
    write list = @zixun

whinfo -u 能够看到用户了，用zixun组的用户能进pub和backup目录，但home目录无法进入
还有我的ttyv0终端经常有nmbd和winbind的信息提示，这是否正常，附件
