pam_winbind - PAM module for Winbind
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.
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.
Gives debugging output to syslog.
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,
a alias-SID or even a 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.
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.
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.
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
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.
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.
Do not emit any messages.
