Generally, an authentication module may have access to more information about a user than their authentication token\&. This function is used to make such information available to the application\&. It should only be called +\fIafter\fR +the user has been authenticated but before a session has been established\&. +.PP +Valid flags, which may be logically OR\*(Aqd with +\fIPAM_SILENT\fR, are: +.PP +PAM_SILENT +.RS 4 +Do not emit any messages\&. +.RE +.PP +PAM_ESTABLISH_CRED +.RS 4 +Initialize the credentials for the user\&. +.RE +.PP +PAM_DELETE_CRED +.RS 4 +Delete the credentials associated with the authentication service\&. +.RE +.PP +PAM_REINITIALIZE_CRED +.RS 4 +Reinitialize the user credentials\&. +.RE +.PP +PAM_REFRESH_CRED +.RS 4 +Extend the lifetime of the user credentials\&. +.RE +.PP +The way the +\fBauth\fR +stack is navigated in order to evaluate the +\fBpam_setcred\fR() function call, independent of the +\fBpam_sm_setcred\fR() return codes, is exactly the same way that it was navigated when evaluating the +\fBpam_authenticate\fR() library call\&. Typically, if a stack entry was ignored in evaluating +\fBpam_authenticate\fR(), it will be ignored when libpam evaluates the +\fBpam_setcred\fR() function call\&. Otherwise, the return codes from each module specific +\fBpam_sm_setcred\fR() call are treated as +\fBrequired\fR\&. +.SH "RETURN VALUES" +.PP +PAM_CRED_UNAVAIL +.RS 4 +This module cannot retrieve the user\*(Aqs credentials\&. +.RE +.PP +PAM_CRED_EXPIRED +.RS 4 +The user\*(Aqs credentials have expired\&. +.RE +.PP +PAM_CRED_ERR +.RS 4 +This module was unable to set the credentials of the user\&. +.RE +.PP +PAM_SUCCESS +.RS 4 +The user credential was successfully set\&. +.RE +.PP +PAM_USER_UNKNOWN +.RS 4 +The user is not known to this authentication module\&. +.RE +.PP +These, non\-\fIPAM_SUCCESS\fR, return values will typically lead to the credential stack +\fIfailing\fR\&.
