| 2 | pam_winbind is a PAM module that can authenticate users against the local domain by talking to the Winbind daemon.

|

|
|---|
| 5 | pam_winbind supports several options which can either be set in
|
|---|
| 6 | the PAM configuration files or in the pam_winbind configuration
|
|---|
| 7 | file situated at
|
|---|
| 8 | <code class="filename">/etc/security/pam_winbind.conf</code>. Options
|
|---|
| 9 | from the PAM configuration file take precedence to those from
|
|---|
| 10 | the configuration file.

|
|---|
| 13 | If this option is set, pam_winbind will only succeed if the user is a member of the given SID or NAME. A SID
|
|---|
| 14 | 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
|
|---|
| 15 | SID. That name must have the form: <em class="parameter"><code>MYDOMAIN\\mygroup</code></em> or
|
|---|
| 16 | <em class="parameter"><code>MYDOMAIN\\myuser</code></em>. pam_winbind will, in that case, lookup the SID internally. Note that
|
|---|
| 17 | NAME may not contain any spaces. It is thus recommended to only use SIDs. You can verify the list of SIDs a
|
|---|
| 18 | user is a member of with <code class="literal">wbinfo --user-sids=SID</code>.

|
|---|
| 20 | By default, pam_winbind tries to get the authentication token from a previous module. If no token is available
|
|---|
| 21 | it asks the user for the old password. With this option, pam_winbind aborts with an error if no authentication
|
|---|
| 22 | token from a previous module is available.
|
|---|
| 23 | </p></dd><dt><span class="term">use_authtok</span></dt><dd><p>
|
|---|
| 24 | Set the new password to the one provided by the previously stacked password module. If this option is not set
|
|---|
| 25 | pam_winbind will ask the user for the new password.

| 26 | </p></dd><dt><span class="term">krb5_auth</span></dt><dd><p>
|
|---|
| 27 |
|
|---|
| 28 | pam_winbind can authenticate using Kerberos when winbindd is
|
|---|
| 29 | talking to an Active Directory domain controller. Kerberos
|
|---|
| 30 | authentication must be enabled with this parameter. When
|
|---|
| 31 | Kerberos authentication can not succeed (e.g. due to clock
|
|---|
| 32 | skew), winbindd will fallback to samlogon authentication over
|
|---|
| 33 | MSRPC. When this parameter is used in conjunction with
|
|---|
| 34 | <em class="parameter"><code>winbind refresh tickets</code></em>, winbind will
|
|---|
| 35 | keep your Ticket Granting Ticket (TGT) uptodate by refreshing
|
|---|
| 36 | it whenever necessary.

|

| 39 |
|
|---|
| 40 | When pam_winbind is configured to try kerberos authentication
|
|---|
| 41 | by enabling the <em class="parameter"><code>krb5_auth</code></em> option, it can
|
|---|
| 42 | store the retrieved Ticket Granting Ticket (TGT) in a
|
|---|
| 43 | credential cache. The type of credential cache can be set with
|
|---|
| 44 | this option. Currently the only supported value is:
|
|---|
| 45 | <em class="parameter"><code>FILE</code></em>. In that case a credential cache in
|
|---|
| 46 | the form of /tmp/krb5cc_UID will be created, where UID is
|
|---|
| 47 | replaced with the numeric user id. Leave empty to just do
|
|---|
| 48 | kerberos authentication without having a ticket cache after the
|
|---|
| 49 | logon has succeeded.

|

| 52 | Winbind allows to logon using cached credentials when <em class="parameter"><code>winbind offline logon</code></em> is enabled. To use this feature from the PAM module this option must be set.
