[Samba] Problem migration samba 2.2.8 -> 3.0.1

[Xavier DRONIOU]

I've two files server on Solaris 2.8 on which i've samba 2.2.8a 
fonctionnal
I've try samba 3 on one server and now my users from windows NT can't 
mount there unix home via samba 
here a copy of smb.conf

I use security = share to allow one user to mount many account because 
windows does not allow multiple uses sessions identification

I've this error on NT station "le type de ressource réseau est incorrect" 

Here a copy of log.smbd
log.smbd :

If i reuse samba 2.2.8 all is fonctionnal but i need samba version 3 to 
make performance test on NT ( version 2.2.8 seems to fall when 
manipulating many files)
I found this on log.smbd
log.smbd: Failed to set socket option SO_KEEPALIVE (Error Invalid 
argument) 
log.smbd:[2004/01/13 14:39:22, 0] lib/util_sock.c:set_socket_options(160)

I think it could generate an error for NT workstation (it work for win2k) 
because packet size is to huge for NT to manage. There is some proble with 
configure about net/if.h and sys/id.h how i can correct the use of socket 
option ?
