+.SH "DESCRIPTION"
+.PP
+The
+\fBpam_sm_setcred\fR
+function is the service module's implementation of the
+\fBpam_setcred\fR(3)
+interface.
+.PP
+This function performs the task of altering the credentials of the user with respect to the corresponding authorization scheme. 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'd with
+\fIPAM_SILENT\fR, are:
+.TP 3n
+PAM_SILENT
+Do not emit any messages.
+.TP 3n
+PAM_DELETE_CRED
+Delete the credentials associated with the authentication service.
+.TP 3n
+PAM_REINITIALIZE_CRED
+Reinitialize the user credentials.
+.TP 3n
+PAM_REFRESH_CRED
+Extend the lifetime of the user credentials.
+.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"
+.TP 3n
+PAM_CRED_UNAVAIL
+This module cannot retrieve the user's credentials.
+.TP 3n
+PAM_CRED_EXPIRED
+The user's credentials have expired.
+.TP 3n
+PAM_CRED_ERR
+This module was unable to set the credentials of the user.
+.TP 3n
+PAM_SUCCESS
+The user credential was successfully set.
+.TP 3n
+PAM_USER_UNKNOWN
+The user is not known to this authentication module.
+.PP
+These, non\-\fIPAM_SUCCESS\fR, return values will typically lead to the credential stack
+\fIfailing\fR. The first such error will dominate in the return value of
+\fBpam_setcred\fR().
