[Samba] domain not available

[deconya]

Hi list

Im using samba 3.5.6 with openldap in a debian squeeze using a domain,
and now Im with a problem inside the LAN using roaming profiles, only I
can't join in the domain. Appears "domain not available" message.

My smb.conf

 [profiles]
   comment = Users profiles
   path = /var/lib/samba/profiles
   browseable = no
   writable = yes
   read only = no
   create mask = 0700
   directory mask = 0700
   csc policy = disable
   force user = %U
   map system = no
   map hidden = no
   map archive = no
   map readonly = no
   ea support = yes
   store dos attributes = yes

And log error is:

[2013/06/05 12:13:27.683220,  1, pid=4095, effective(0, 0), real(0, 0)]
[2013/06/05 12:13:27.683266,  2, pid=4095, effective(0, 0), real(0,
0)]   getpeername failed. Error was Transport endpoint is not connected
  pid[4095] Error writing 4 bytes to client 0.0.0.0. -1. (Connection
reset by peer)

Where can be the problem?

Thanks
