Sftp chroot + winbind + ad

$

I have next configuration :
- AIX 5.3 (5300-11-03-1013)
- pWare.SAMBA 3.5.8.1
- OpenSSH 5.2.0
- OpenSSL 0.9.8

Now, to be more clearly I'll explain what I need indeed.
My task is set up integration AIX server to Active Directory 2008 with Samba (Winbind) for chrooted SSH connections.
It means our developers should login into AIX server by own AD acounts with SFTP and upload/download files on it.
Chroot environment is recommended for it.

Ok, lets look at my krb5.conf

Code:

[root@wb53tst /]$ cat /etc/krb5/krb5.conf
[libdefaults]
        default_realm = TST.TST
        default_keytab_name = FILE:/etc/krb5/krb5.keytab
        default_tkt_enctypes = des3-cbc-sha1 arcfour-hmac aes256-cts des-cbc-md5 des-cbc-crc aes128-cts
        default_tgs_enctypes = des3-cbc-sha1 arcfour-hmac aes256-cts des-cbc-md5 des-cbc-crc aes128-cts

[realms]
        TST.TST = {
                kdc = dc1.tst.com:88
                admin_server = dc1.tst.com:749
                default_domain = tst.com
        }

[domain_realm]
        .tst.com = TST.COM
        dc1.tst.com = TST.COM

[logging]
        kdc = FILE:/var/krb5/log/krb5kdc.log
        admin_server = FILE:/var/krb5/log/kadmin.log
        kadmin_local = FILE:/var/krb5/log/kadmin_local.log
        default = FILE:/var/krb5/log/krb5lib.log

and smb.conf
Code:

[root@wb53tst /]$ cat /opt/pware/lib/smb.conf
[global]
        workgroup = TST
        netbios name = wb53tst
        security = ads
        passdb backend = tdbsam
        realm = TST.COM
        password server = dc1.tst.com
        load printers = yes
        cups options = raw

winbind uid = 10000-65534
winbind gid = 10000-65534
winbind use default domain = yes
winbind separator = +

winbind enum users = yes
winbind enum groups = yes
winbind cache time = 60
winbind uid = 10000-65534
winbind gid = 10000-65534
winbind use default domain = yes
winbind separator = +

template homedir = /home/FILEBASE/TST/%U
template shell = /bin/bash
winbind offline logon = no

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

Then create dirs ...
Code:

[root@wb53tst /]$ mkdir -p /home/FILEBASE/TST
After that we set option for create home dirs automaticaly
Code:

[root@wb53tst /]$ vi /etc/security/login.cfg
...
mkhomeatlogin = true

Now we should edit /etc/security/user config file for authentificate new users in our system with Winbind
Code:

default:
...
        SYSTEM = "WINBIND OR compat"
        registry = WINBIND
...

Eventually we join our server in AD and trying to login on it with ssh from other station (PC, or server)
Code:

[root@wb53tst /]$ net ads join -U aixadmin
Password:
[root@wb53tst /]$ wbinfo -u | grep a.fox
a.fox
[root@wb53tst /]$ lsuser -r WINBIND a.fox
a.fox id=10000 pgrp=domain users home=/home/FILEBASE/TST/a.fox shell=/bin/bash gecos= login=true su=true rlogin=true daemon=true admin=false sugroups=ALL

Code:

$ ssh -l a.fox wb53tst.tst.com
Password:
[a.fox@wb53tst ~]$ pwd
/home/FILEBASE/TST/a.fox

Well. It works. But what should I do for chroot AD users ?
In /etc/ssh/sshd_config option:
ChrootDirectory /home/FILEBASE/TST/%u
Doesn't work. Any idea ?
