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.

SEE ALSO
       pam_keyinit(8)

AUTHORS
       The cifscreds program was originally developed by Igor Druzhinin <jaxbrigs@gmail.com>.
       This manpage and a redesign of the code was done by Jeff Layton <jlayton@samba.org>.
