+.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:
+.PP
+PAM_SILENT
+.RS 4
+Do not emit any messages\.
+.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\'s credentials\.
+.RE
+.PP
+PAM_CRED_EXPIRED
+.RS 4
+The user\'s 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\. The first such error will dominate in the return value of
+\fBpam_setcred\fR()\.
