SYNOPSIScifscreds 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.
