PAM_SM_CHAUTHTOK(3)		   BSD Library Functions Manual 	      PAM_SM_CHAUTHTOK(3)

     pam_sm_chauthtok -- service module implementation for pam_chauthtok

     Pluggable Authentication Module Library (libpam, -lpam)

     #include <sys/types.h>
     #include <security/pam_appl.h>
     #include <security/pam_modules.h>

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

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

     When the application calls pam_chauthtok(3), the service function is called twice, first
     with the PAM_PRELIM_CHECK flag set and then again with the PAM_UPDATE_AUTHTOK flag set.

     The pam_sm_chauthtok function returns one of the following values:

     [PAM_ABORT]	 General failure.

			 Authentication token aging disabled.

     [PAM_AUTHTOK_ERR]	 Authentication token failure.

			 Authentication token lock busy.

			 Failed to recover old authentication token.

     [PAM_BUF_ERR]	 Memory buffer error.

     [PAM_CONV_ERR]	 Conversation failure.

     [PAM_IGNORE]	 Ignore this module.

     [PAM_PERM_DENIED]	 Permission denied.

     [PAM_SERVICE_ERR]	 Error in service module.

     [PAM_SYSTEM_ERR]	 System error.

     [PAM_TRY_AGAIN]	 Try again.

     The pam_sm_chauthtok function and this manual page were developed for the FreeBSD Project by
     ThinkSec AS and Network Associates Laboratories, the Security Research Division of Network
     Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the
     DARPA CHATS research program.
