Note, however, the following two options are +\fImutually exclusive\fR\&. +.RE +.PP +PAM_PRELIM_CHECK +.RS 4 +This indicates that the modules are being probed as to their ready status for altering the user\*(Aqs authentication token\&.

If the flag is logically OR\*(Aqd with +\fBPAM_CHANGE_EXPIRED_AUTHTOK\fR, the token is only changed if it has actually expired\&. +.RE +.PP +The PAM library calls this function twice in succession\&. The first time with +\fBPAM_PRELIM_CHECK\fR +and then, if the module does not return +\fBPAM_TRY_AGAIN\fR, subsequently with +\fBPAM_UPDATE_AUTHTOK\fR\&.
