Enabling Kerberos (extended security) works when CONFIG_CIFS_EXPERIMENTAL is
on but requires a user space helper (from the Samba project). NTLM and NTLMv2 and
LANMAN support do not require this helper.
Enabling Kerberos (extended security) works but requires version 1.2 or later
of the helper program cifs.upcall to be present and to be configured in the
/etc/request-key.conf file. The cifs.upcall helper program is from the Samba
project(http://www.samba.org). NTLM and NTLMv2 and LANMAN support do not
require this helper. Note that NTLMv2 security (which does not require the
cifs.upcall helper program), instead of using Kerberos, is sufficient for
some use cases.
Enabling DFS support (used to access shares transparently in an MS-DFS
global name space) requires that CONFIG_CIFS_EXPERIMENTAL be enabled. In
addition, DFS support for target shares which are specified as UNC
names which begin with host names (rather than IP addresses) requires
a user space helper (such as cifs.upcall) to be present in order to
translate host names to ip address, and the user space helper must also
be configured in the file /etc/request-key.conf
To use cifs Kerberos and DFS support, the Linux keyutils package should be
installed and something like the following lines should be added to the
/etc/request-key.conf file:
create cifs.spnego * * /usr/local/sbin/cifs.upcall %k
create dns_resolver * * /usr/local/sbin/cifs.upcall %k
