Имя (Name)

pam_sm_authenticate - PAM service function for user authentication


Синопсис (Synopsis)

#define PAM_SM_AUTH

#include <security/pam_modules.h>

int pam_sm_authenticate(pam_handle_t *pamh, int flags, int argc, const char **argv);


Описание (Description)

The pam_sm_authenticate function is the service module's implementation of the pam_authenticate(3) interface.

This function performs the task of authenticating the user.

Valid flags, which may be logically OR'd with PAM_SILENT, are:

PAM_SILENT Do not emit any messages.

PAM_DISALLOW_NULL_AUTHTOK Return PAM_AUTH_ERR if the database of authentication tokens for this authentication mechanism has a NULL entry for the user. Without this flag, such a NULL token will lead to a success without the user being prompted.


Возвращаемое значение (Return value)

PAM_AUTH_ERR Authentication failure.

PAM_CRED_INSUFFICIENT For some reason the application does not have sufficient credentials to authenticate the user.

PAM_AUTHINFO_UNAVAIL The modules were not able to access the authentication information. This might be due to a network or hardware failure etc.

PAM_SUCCESS The authentication token was successfully updated.

PAM_USER_UNKNOWN The supplied username is not known to the authentication service.

PAM_MAXTRIES One or more of the authentication modules has reached its limit of tries authenticating the user. Do not try again.
