[Samba] samba PDC, cannot add windows workstations

[Viji V Nair]

Hi,

I have setup samba as a PDC with kerberos and ldap. While adding the windows
clients I get the following error message on the logs, and windows says the
user name and password is incorrect

[2008/12/31 19:00:09,  0] lib/util_sock.c:write_data(1059)
[2008/12/31 19:00:09,  0] lib/util_sock.c:get_peer_addr_internal(1607)
  getpeername failed. Error was Transport endpoint is not connected
  write_data: write failure in writing to client 0.0.0.0. Error Connection
reset by peer
[2008/12/31 19:00:09,  0] smbd/process.c:srv_send_smb(74)
  Error writing 4 bytes to client. -1. (Transport endpoint is not connected)

Any help on the same will be gratly appreciated.
