pam_acct_mgmt: PAM account validation management


pam_acct_mgmt - PAM account validation management


#include <security/pam_appl.h> int pam_acct_mgmt(pam_handle_t *pamh, int flags);


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.


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.
