If I understand the "multiuser" option correctly it should

to use Kerberos credentials stored during login if sec=krb5 or sec=krb5i
is used. For NTLM there is pam_cifscreds which can be added to the PAM
configuration. You might have to add the 'forward_pass' to pam_sss.so in
the auth section as well to make sure pam_sss will put the password on
the PAM stack for other modules.
You do indeed understand the option correctly. We use sec=krb5,multiuser
quite happily that way, getcifsacl returns sensible information, and access is
controlled using per-user krb5 as expected.
