NAME
pam_acct_mgmt - PAM account validation management SYNOPSIS
#include <security/pam_appl.h> int pam_acct_mgmt(pam_handle_t *pamh, int flags); DESCRIPTION
The pam_acct_mgmt function is used to determine if the users account is valid. It checks for authentication token and account expiration and verifies access restrictions. It is typically called after the user has been authenticated. The pamh argument is an authentication handle obtained by a prior call to pam_start(). The flags argument is the binary or of zero or more of the following values: PAM_SILENT Do not emit any messages. PAM_DISALLOW_NULL_AUTHTOK The PAM module service should return PAM_NEW_AUTHTOK_REQD if the user has a null authentication token. RETURN VALUES
PAM_ACCT_EXPIRED User account has expired. PAM_AUTH_ERR Authentication failure. PAM_NEW_AUTHTOK_REQD The user account is valid but their authentication token is expired. The correct response to this return-value is to require that the user satisfies the pam_chauthtok() function before obtaining service. It may not be possible for some applications to do this. In such cases, the user should be denied access until such time as they can update their password. PAM_PERM_DENIED Permission denied. PAM_SUCCESS The authentication token was successfully updated. PAM_USER_UNKNOWN User unknown to password service. SEE ALSO

NAME
pam_authenticate - account authentication SYNOPSIS
#include <security/pam_appl.h> int pam_authenticate(pam_handle_t *pamh, int flags); DESCRIPTION
The pam_authenticate function is used to authenticate the user. The user is required to provide an authentication token depending upon the authentication service, usually this is a password, but could also be a finger print. The PAM service module may request that the user enter their username vio the the conversation mechanism (see pam_start(3) and pam_conv(3)). The name of the authenticated user will be present in the PAM item PAM_USER. This item may be recovered with a call to pam_get_item(3). The pamh argument is an authentication handle obtained by a prior call to pam_start(). The flags argument is the binary or of zero or more of the following values: PAM_SILENT Do not emit any messages. PAM_DISALLOW_NULL_AUTHTOK The PAM module service should return PAM_AUTH_ERR if the user does not have a registered authentication token. RETURN VALUES
PAM_ABORT The application should exit immediately after calling pam_end(3) first. PAM_AUTH_ERR The user was not authenticated. PAM_CRED_INSUFFICIENT For some reason the application does not have sufficient credentials to authenticate the user. PAM_AUTHINFO_UNVAIL The modules were not able to access the authentication information. This might be due to a network or hardware failure etc. PAM_MAXTRIES One or more of the authentication modules has reached its limit of tries authenticating the user. Do not try again. PAM_SUCCESS The user was successfully authenticated. PAM_USER_UNKNOWN User unknown to authentication service. SEE ALSO
