Linux-PAM Manual
pam_xauth_data
structure containing X authentication data
#include <security/pam_appl.h>
struct pam_xauth_data {
int namelen;
char *name;
int datalen;
char *data;
};
DESCRIPTION
The pam_xauth_data structure contains X
authentication data used to make a connection to an X display.
Using this mechanism, an application can communicate X
authentication data to PAM service modules. This allows modules to
make a connection to the user's X display in order to label the
user's session on login, display visual feedback or for other
purposes.
The name field contains the name of the
authentication method, such as "MIT-MAGIC-COOKIE-1". The
namelen field contains the length of this string,
not including the trailing NUL character.
The data field contains the authentication
method-specific data corresponding to the specified name. The
datalen field contains its length in bytes.
The X authentication data can be changed with the
PAM_XAUTH_DATA item. It can be queried and
set with
pam_get_item3
and
pam_set_item 3
respectively. The value used to set it should be
a pointer to a pam_xauth_data structure. An internal copy of both
the structure itself and its fields is made by PAM when setting the
item.
