NAME

       pam_sm_acct_mgmt - PAM service function for account management

SYNOPSIS

       #define PAM_SM_ACCOUNT

       #include <security/pam_modules.h>

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

DESCRIPTION

       The pam_sm_acct_mgmt function is the service module's implementation of the pam_acct_mgmt(3) interface.

       This function performs the task of establishing whether the user is permitted to gain access at this time. It should be understood that the
       user has previously been validated by an authentication module. This function checks for other things. Such things might be: the time of
       day or the date, the terminal line, remote hostname, etc. This function may also determine things like the expiration on passwords, and
       respond that the user change it before continuing.

       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.

RETURN VALUES

       PAM_ACCT_EXPIRED
	   User account has expired.

       PAM_AUTH_ERR
	   Authentication failure.

       PAM_NEW_AUTHTOK_REQD
	   The user's authentication token has expired. Before calling this function again the application will arrange for a new one to be given.
	   This will likely result in a call to pam_sm_chauthtok().

       PAM_PERM_DENIED
	   Permission denied.

       PAM_SUCCESS
	   The authentication token was successfully updated.

       PAM_USER_UNKNOWN
	   User unknown to password service.

NAME

       pam_sm_chauthtok - PAM service function for authentication token management

SYNOPSIS

       #define PAM_SM_PASSWORD

       #include <security/pam_modules.h>

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

DESCRIPTION

       The pam_sm_chauthtok function is the service module's implementation of the pam_chauthtok(3) interface.

       This function is used to (re-)set the authentication token of the user.

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

       PAM_SILENT
	   Do not emit any messages.

       PAM_CHANGE_EXPIRED_AUTHTOK
	   This argument indicates to the module that the users authentication token (password) should only be changed if it has expired. This
	   flag is optional and must be combined with one of the following two flags. Note, however, the following two options are mutually
	   exclusive.

       PAM_PRELIM_CHECK
	   This indicates that the modules are being probed as to their ready status for altering the user's authentication token. If the module
	   requires access to another system over some network it should attempt to verify it can connect to this system on receiving this flag.
	   If a module cannot establish it is ready to update the user's authentication token it should return PAM_TRY_AGAIN, this information
	   will be passed back to the application.

	   If the control value sufficient is used in the password stack, the PAM_PRELIM_CHECK section of the modules following that control value
	   is not always executed.

       PAM_UPDATE_AUTHTOK
	   This informs the module that this is the call it should change the authorization tokens. If the flag is logically OR'd with
	   PAM_CHANGE_EXPIRED_AUTHTOK, the token is only changed if it has actually expired.

       The PAM library calls this function twice in succession. The first time with PAM_PRELIM_CHECK and then, if the module does not return
       PAM_TRY_AGAIN, subsequently with PAM_UPDATE_AUTHTOK. It is only on the second call that the authorization token is (possibly) changed.

RETURN VALUES

       PAM_AUTHTOK_ERR
	   The module was unable to obtain the new authentication token.

       PAM_AUTHTOK_RECOVERY_ERR
	   The module was unable to obtain the old authentication token.

       PAM_AUTHTOK_LOCK_BUSY
	   Cannot change the authentication token since it is currently locked.

       PAM_AUTHTOK_DISABLE_AGING
	   Authentication token aging has been disabled.

       PAM_PERM_DENIED
	   Permission denied.

       PAM_TRY_AGAIN
	   Preliminary check was unsuccessful. Signals an immediate return to the application is desired.

       PAM_SUCCESS
	   The authentication token was successfully updated.

       PAM_USER_UNKNOWN
	   User unknown to password service.
