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.
