NAME
cifscreds - manage NTLM credentials in kernel keyring
SYNOPSIS
cifscreds add|clear|clearall|update [-u username] [-d] host|domain
DESCRIPTION
The cifscreds program is a tool for managing credentials (username and password) for the purpose of
establishing sessions in multiuser mounts.
When a cifs filesystem is mounted with the "multiuser" option, and does not use krb5 authentication, it
needs to be able to get the credentials for each user from somewhere. The cifscreds program is the tool
used to provide these credentials to the kernel.
The first non-option argument to cifscreds is a command (see the COMMANDS section below). The second non-
option argument is a hostname or address, or an NT domain name.
COMMANDS
add Add credentials to the kernel to be used for connecting to the given server, or servers in the given
domain.
clear
Clear credentials for a particular host or domain from the kernel.
clearall
Clear all cifs credentials from the kernel.
update
Update stored credentials in the kernel with a new username and password.
OPTIONS
-d, --domain
The provided host/domain argument is a NT domainname.
Ordinarily the second argument provided to cifscreds is treated as a hostname or IP address. This
option causes the cifscreds program to treat that argument as an NT domainname instead.
If there are not host specific credentials for the mounted server, then the kernel will next look for
a set of domain credentials equivalent to the domain= option provided at mount time.
-u, --username
Ordinarily, the username is derived from the unix username of the user adding the credentials. This
option allows the user to substitute a different username.
NOTES
The cifscreds utility requires a kernel built with support for the login key type. That key type was
added in v3.3 in mainline Linux kernels.
Since cifscreds adds keys to the session keyring, it is highly recommended that one use pam_keyinit to
ensure that a session keyring is established at login time.
