NAME

pam_smbfs_login - PAM user credential authentication module for SMB/CIFS client login
 

SYNOPSIS

pam_smb_cred.so.1

DESCRIPTION

The pam_smbfs_login module implements pam_sm_setcred(3PAM) to provide functions that act equivalently to the smbutil(1) login command.

This optional functionality is meant to be used only in environments that do not run Active Directory or Kerberos, but which synchronize passwords between Solaris clients and their CIFS/SMB servers.

This module permits the login password to be stored as if the smbutil(1) login command was used to store a password for PAM_USER in the user or system default domain. The choice of default domain is the first of the following:
-Domain entry specified in the default section of the $HOME/.nsmbrc file, if readable.
-Domain entry specified in the default section shown by the sharectl get smbfs command.
-String WORKGROUP.

Because pam_smbfs_login runs as root during the login process, a $HOME/.nsmbrc file accessed through NFS may only be readable if the file permits reads by others. This conflicts with the requirement that passwords stored in $HOME/.nsmbrc are ignored when permissions are open.

To use this functionality, add the following line to the /etc/pam.conf file:

login  auth optional    pam_smbfs_login.so.1

Authentication service modules must implement both pam_sm_authenticate(3PAM) and pam_sm_setcred(3PAM). In this module, pam_sm_authenticate(3PAM) always returns PAM_IGNORE.

The pam_sm_setcred(3PAM) function accepts the following flags:

PAM_REFRESH_CRED

Returns PAM_IGNORE.

PAM_SILENT

Suppresses messages.

PAM_ESTABLISH_CRED
PAM_REINITIALIZE_CRED

Stores the authentication token for PAM_USER in the same manner as the smbutil(1) login command.

PAM_DELETE_CRED

Deletes the stored password for PAM_USER in the same manner as the smbutil(1) logout command.

The following options can be passed to the pam_smbfs_login module:

debug

Produces syslog(3C) debugging information at the LOG_AUTH or LOG_DEBUG level.

nowarn

Suppresses warning messages.

FILES

$HOME/.nsmbrc

Find default domain, if present.

ERRORS

Upon successful completion of pam_sm_setcred(3PAM), PAM_SUCCESS is returned. The following error codes are returned upon error:

PAM_USER_UNKNOWN

User is unknown.

PAM_AUTHTOK_ERR

Password is bad.

PAM_AUTH_ERR

Domain is bad.

PAM_SYSTEM_ERR

System error.
