| 178 | .SH "OPTIONS"
|

| 179 | .PP
|
|---|
| 180 | pam_winbind supports several options which can either be set in the PAM configuration files or in the pam_winbind configuration file situated at
|
|---|
| 181 | \FC/etc/security/pam_winbind\&.conf\F[]\&. Options from the PAM configuration file take precedence to those from the configuration file\&.

| 193 | require_membership_of=[SID or NAME]
|
|---|
| 194 | .RS 4
|
|---|
| 195 | 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:
|
|---|
| 196 | \fIMYDOMAIN\e\emygroup\fR
|
|---|
| 197 | or
|
|---|
| 198 | \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
|
|---|
| 199 | \FCwbinfo \-\-user\-sids=SID\F[]\&.

|

| 218 | 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
|
|---|
| 219 | \fIwinbind refresh tickets\fR, winbind will keep your Ticket Granting Ticket (TGT) uptodate by refreshing it whenever necessary\&.

|
|---|
| 225 | \fIkrb5_auth\fR
|
|---|
| 226 | 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:
|
|---|
| 227 | \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\&.
