.SH "NAME"
pam_winbind.conf \- Configuration file of PAM module for Winbind
.SH "DESCRIPTION"
.PP
This configuration file is part of the
\fBsamba\fR(7)
suite\&.
.PP
pam_winbind\&.conf is the configuration file for the pam_winbind PAM module\&. See
\fBpam_winbind\fR(8)
for further details\&.
.SH "SYNOPSIS"
.PP
The pam_winbind\&.conf configuration file is a classic ini\-style configuration file\&. There is only one section (global) where various options are defined\&.
.SH "OPTIONS"
.PP
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 pam_winbind\&.conf configuration file\&.
.PP
debug = yes|no
.RS 4
Gives debugging output to syslog\&. Defaults to "no"\&.
.RE
.PP
debug_state = yes|no
.RS 4
Gives detailed PAM state debugging output to syslog\&. Defaults to "no"\&.
.RE
.PP
require_membership_of = [SID or NAME]
.RS 4
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:
\fIMYDOMAIN\e\emygroup\fR
or
\fIMYDOMAIN\e\emyuser\fR\&. 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\&. This setting is empty by default\&.
.RE
.PP
try_first_pass = yes|no
.RS 4
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\&. If a primary password is not valid, PAM will prompt for a password\&. Default to "no"\&.
.RE
.PP
krb5_auth = yes|no
.RS 4
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
\fIwinbind refresh tickets\fR, winbind will keep your Ticket Granting Ticket (TGT) uptodate by refreshing it whenever necessary\&. Defaults to "no"\&.
.RE
.PP
krb5_ccache_type = [type]
.RS 4
When pam_winbind is configured to try kerberos authentication by enabling the
\fIkrb5_auth\fR
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:
\fIFILE\fR\&. 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\&. This setting is empty by default\&.
.RE
.PP
cached_login = yes|no
.RS 4
Winbind allows to logon using cached credentials when
\fIwinbind offline logon\fR
is enabled\&. To use this feature from the PAM module this option must be set\&. Defaults to "no"\&.
.RE
.PP
silent = yes|no
.RS 4
Do not emit any messages\&. Defaults to "no"\&.
.RE
.PP
mkhomedir = yes|no
.RS 4
Create homedirectory for a user on\-the\-fly, option is valid in PAM session block\&. Defaults to "no"\&.
.RE
.PP
warn_pwd_expire = days
.RS 4
Defines number of days before pam_winbind starts to warn about passwords that are going to expire\&. Defaults to 14 days\&.

.SH "VERSION"
.PP
This man page is correct for version 3 of Samba\&.
.SH "AUTHOR"
.PP
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\&.
