.SH "NAME"
pam_cifscreds \- PAM module to manage NTLM credentials in kernel keyring
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Edit the \s-1PAM\s0 configuration files for the systems that you want to
automatically register \s-1NTLM\s0 credentials for, e.g. /etc/pam.d/login,
and modify as follows:
.PP
.Vb 5
\& ...
\& auth substack system\-auth
\& +++ auth optional pam_cifscreds.so
\& auth include postlogin
\& ...
\&
\& ...
\& session include system\-auth
\& +++ session optional pam_cifscreds.so domain=DOMAIN
\& session include postlogin
\& ...
.Ve
.PP
Change \s-1DOMAIN\s0 to the name of you Windows domain, or use host= as
described below.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBpam_cifscreds\fR \s-1PAM\s0 module is a tool for automatically adding
credentials (username and password) for the purpose of establishing
sessions in multiuser mounts.
.PP
When a cifs filesystem is mounted with the \*(L"multiuser\*(R" option, and does
not use krb5 authentication, it needs to be able to get the credentials
for each user from somewhere. The \fBpam_cifscreds\fR module can be used
to provide these credentials to the kernel automatically at login.
.PP
In the session section of the \s-1PAM\s0 configuration file, the module can
either an \s-1NT\s0 domain name or a list of hostname or addresses.
.SH "OPTIONS"
.IX Header "OPTIONS"
\&\fBpam_cifscreds\fR supports a couple options which can be set in the \s-1PAM\s0
configuration files. You must have one (and only one) of domain= or
host=.
.IP "\fBdebug\fR" 4
.IX Item "debug"
Turns on some extra debug logging.
.IP "\fBdomain\fR=<\s-1NT\s0 domain name>" 4
.IX Item "domain=<NT domain name>"
Credentials will be added for the specified \s-1NT\s0 domain name.
.IP "\fBhost\fR=<hostname or \s-1IP\s0 address>[,...]" 4
.IX Item "host=<hostname or IP address>[,...]"
Credentials will be added for the specified hostnames or \s-1IP\s0 addresses.
.SH "NOTES"
.IX Header "NOTES"
The pam_cifscreds \s-1PAM\s0 module requires a kernel built with support for
the \fBlogin\fR key type. That key type was added in v3.3 in mainline Linux
kernels.
.PP
Since \fBpam_cifscreds\fR adds keys to the session keyring, it is highly
recommended that one use \fBpam_keyinit\fR to ensure that a session keyring
is established at login time.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
\&\fIcifscreds\fR\|(1), \fIpam_keyinit\fR\|(8)
.SH "AUTHOR"
.IX Header "AUTHOR"
The pam_cifscreds \s-1PAM\s0 module was developed by Orion Poplawski
<orion@nwra.com>.
