PAM_XAUTH_DATA
PAM_XAUTH_DATA
NAME
pam_xauth_data − structure containing X authentication
data
SYNOPSIS
#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_item(3) 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.
SEE ALSO
pam_start(3),
pam_get_item(3),
STANDARDS
The pam_xauth_data structure and
PAM_XAUTH_DATA item are Linux−PAM
extensions.
