+ cifsacl Report mode bits (e.g. on stat) based on the Windows ACL for
+ the file. (EXPERIMENTAL)
+ servern Specify the server 's netbios name (RFC1001 name) to use
+ when attempting to setup a session to the server.
+ This is needed for mounting to some older servers (such
+ as OS/2 or Windows 98 and Windows ME) since they do not
+ support a default server name. A server name can be up
+ to 15 characters long and is usually uppercased.
+ sfu When the CIFS Unix Extensions are not negotiated, attempt to
+ create device files and fifos in a format compatible with
+ Services for Unix (SFU). In addition retrieve bits 10-12
+ of the mode via the SETFILEBITS extended attribute (as
+ SFU does). In the future the bottom 9 bits of the
+ mode also will be emulated using queries of the security
+ descriptor (ACL).
+ sign Must use packet signing (helps avoid unwanted data modification
+ by intermediate systems in the route). Note that signing
+ does not work with lanman or plaintext authentication.
+ seal Must seal (encrypt) all data on this mounted share before
+ sending on the network. Requires support for Unix Extensions.
+ Note that this differs from the sign mount option in that it
+ causes encryption of data sent over this mounted share but other
+ shares mounted to the same server are unaffected.
+ locallease This option is rarely needed. Fcntl F_SETLEASE is
+ used by some applications such as Samba and NFSv4 server to
+ check to see whether a file is cacheable. CIFS has no way
+ to explicitly request a lease, but can check whether a file
+ is cacheable (oplocked). Unfortunately, even if a file
+ is not oplocked, it could still be cacheable (ie cifs client
+ could grant fcntl leases if no other local processes are using
+ the file) for cases for example such as when the server does not
+ support oplocks and the user is sure that the only updates to
+ the file will be from this client. Specifying this mount option
+ will allow the cifs client to check for leases (only) locally
+ for files which are not oplocked instead of denying leases
+ in that case. (EXPERIMENTAL)
+ sec Security mode. Allowed values are:
+ none attempt to connection as a null user (no name)
+ krb5 Use Kerberos version 5 authentication
+ krb5i Use Kerberos authentication and packet signing
+ ntlm Use NTLM password hashing (default)
+ ntlmi Use NTLM password hashing with signing (if
+ /proc/fs/cifs/PacketSigningEnabled on or if
+ server requires signing also can be the default)
+ ntlmv2 Use NTLMv2 password hashing
+ ntlmv2i Use NTLMv2 password hashing with packet signing
+ lanman (if configured in kernel config) use older
+ lanman hash
+hard Retry file operations if server is not responding
+soft Limit retries to unresponsive servers (usually only
+ one retry) before returning an error. (default)
