PAM_WINBIND(7) 7 PAM_WINBIND(7)
NAME
pam_winbind - PAM module for Winbind
DESCRIPTION
This tool is part of the samba(7) suite.
pam_winbind is a PAM module that can authenticate users against the local domain by talking to the Winbind daemon.
OPTIONS
pam_winbind supports several options which can either be set in the PAM configuration files or in the pam_winbind configuration file
situated at /etc/security/pam_winbind.conf. Options from the PAM configuration file take precedence to those from the configuration file.
debug
Gives debugging output to syslog.
debug_state
Gives detailed PAM state debugging output to syslog.
require_membership_of=[SID or NAME]
If this option is set, pam_winbind will only succeed if the user is a member of the given SID or NAME. A SID can be either a group-SID,
an alias-SID or even an user-SID. It is also possible to give a NAME instead of the SID. That name must have the form:
MYDOMAIN\mygroup or MYDOMAIN\myuser. pam_winbind will, in that case, lookup the SID internally. Note that NAME may not contain any
spaces. It is thus recommended to only use SIDs. You can verify the list of SIDs a user is a member of with wbinfo --user-sids=SID.
try_first_pass
use_first_pass
By default, pam_winbind tries to get the authentication token from a previous module. If no token is available it asks the user for the
old password. With this option, pam_winbind aborts with an error if no authentication token from a previous module is available.
use_authtok
Set the new password to the one provided by the previously stacked password module. If this option is not set pam_winbind will ask the
user for the new password.
krb5_auth
pam_winbind can authenticate using Kerberos when winbindd is talking to an Active Directory domain controller. Kerberos authentication
must be enabled with this parameter. When Kerberos authentication can not succeed (e.g. due to clock skew), winbindd will fallback to
samlogon authentication over MSRPC. When this parameter is used in conjunction with winbind refresh tickets, winbind will keep your
Ticket Granting Ticket (TGT) uptodate by refreshing it whenever necessary.
krb5_ccache_type=[type]
When pam_winbind is configured to try kerberos authentication by enabling the krb5_auth option, it can store the retrieved Ticket
Granting Ticket (TGT) in a credential cache. The type of credential cache can be set with this option. Currently the only supported
value is: FILE. In that case a credential cache in the form of /tmp/krb5cc_UID will be created, where UID is replaced with the numeric
user id. Leave empty to just do kerberos authentication without having a ticket cache after the logon has succeeded.
cached_login
Winbind allows to logon using cached credentials when winbind offline logon is enabled. To use this feature from the PAM module this
option must be set.
silent
Do not emit any messages.

The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.

Samba(7) delivers the set of four SMF(5) services as can be seen from the following example:
$ svcs samba wins winbind swat
STATE STIME FMRI
disabled Apr_21 svc:/network/samba:default
disabled Apr_21 svc:/network/winbind:default
disabled Apr_21 svc:/network/wins:default
disabled Apr_21 svc:/network/swat:default
where the services are:
"samba"
runs the smbd daemon managing the CIFS sessions
"wins"
runs the nmbd daemon enabling the browsing (WINS)
"winbind"
runs the winbindd daemon making the domain idmap
"swat"
Samba Web Administration Tool is a service providing access to browser-based Samba administration interface and on-line documentation.
The service runs on software loopback network interface on port 901/tcp, i.e. opening "http://localhost:901/" in browser will access
the SWAT service on local machine.
Please note: SWAT uses HTTP Basic Authentication scheme where user name and passwords are sent over the network in clear text. In the SWAT
case the user name is root. Transferring such sensitive data is advisable only on the software loopback network interface or over secure
networks.
