Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize) also
now allowing support for specifying client netbiosname. NT4 support added.

Servers must support the NTLM SMB dialect (which is the most recent, supported
by Samba and Windows NT

ervers must support either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC

S
ervers must support either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC
1001/1002 support for "Netbios-Over-TCP/IP." Neither of these is likely to be a
problem as most servers support this. IPv6 support is planned for the future.

3) create of new files to FAT partitions on Windows servers can
succeed but still return access denied (appears to be Windows
not client problem). NTFS partitions do not have this problem.
4) debug connectathon special test case nfs_idem (which does
some invalid symlink naming, or at least what Samba thinks
is an invalid symlink target).
5) debug connectation lock test case 10 which fails against
Samba (may be unmappable due to POSIX to Windows lock model
differences but worth investigating). Also debug Samba to
see why lock test case 7 takes longer to complete to Samba
than to Windows.
Misc testing to do
=================
1) check out max path names and max path name components against various server
types.
2)
Run dbench.
Modify file portion of ltp so it can run against a mounted network
2) Modify file portion of ltp so it can run against a mounted network
share and run it against cifs vfs.

there are some easy changes that can be done to parallelize sequential writes,
and when signing is disabled to request larger read sizes (larger than
negotiated size) and send larger write sizes to modern servers.
