nomapchars Do not translate any of these seven characters (default).
nocase Request case insensitive path name matching (case
sensitive is the default if the server suports it).
+ posixpaths If CIFS Unix extensions are supported, attempt to
+ negotiate posix path name support which allows certain
+ characters forbidden in typical CIFS filenames, without
+ requiring remapping. (default)
+ noposixpaths If CIFS Unix extensions are supported, do not request
+ posix path name support (this may cause servers to
+ reject creatingfile with certain reserved characters).
nobrl Do not send byte range lock requests to the server.
This is necessary for certain applications that break
with cifs style mandatory byte range locks (and most
SFU does). In the future the bottom 9 bits of the mode
mode also will be emulated using queries of the security
descriptor (ACL).
-
+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

The mount.cifs mount helper also accepts a few mount options before -o
