need help for winbind PLEASE

[Brunet Eric]

hello,

I have some problems to authentificate domain users on a samba server 
(2.2.2, member of same domain).
i read all samba docs and browsed many archives, i didn't see the case 
of samba PDC with samba member, it's always samba member with NT4 or 
WIN2000 PDC.
So my first question is: is it possible???

my situation is following:
-samba PDC(v2.2.2) work fine with all windows clients
-samba member(v2.2.2) it seems correctly configured:
-in smb.conf: security = domain, winbind parameters .....)
-pam : add pam_winbind.so in different files of /etc/pam.d

About winbindd:
#wbinfo -t
Secret is good
#wbinfo -u
...
OFFICE+foo
...
notice: foo is an account of my domain OFFICE
# wbinfo -g
OFFICE+Domain Admins
OFFICE+Domain Users

# wbinfo -r OFFICE+ericb
10003
ok all seems to wrok
BUT:
# wbinfo -a OFFICE+foo%xxxxx
plaintext password authentication succeeded
                                                        """"""""""
challenge/response password authentication failed
                                                                        
""""""
Could not authenticate user OFFICE+foo%xxxxx with challenge/response
Notice: of course there aren't account system "foo" in the samba member 
machine
So why plaintext authentification rocks only??? is it normal????

#wbinfo -m
#
->no response????? it might display OFFICE domain

i give you the log of winbind(with debug option  to 3) when i tried to 
connect at a share directory in the member machine with:
#smbclient //member/test -U foo -W OFFICE
