+.SH DESCRIPTION
+.B pam_setcred
+
+This function is used to establish, maintain and delete the
+credentials of a user. It should be called after a user has been
+authenticated and before a session is opened for the user (with
+.BR pam_open_session "(3))."
+
+It should be noted that credentials come in many forms. Examples
+include: group memberships; ticket-files; and Linux-PAM environment
+variables.  For this reason, it is important that the basic identity
+of the user is established, by the application, prior to a call to
+this function.  For example, the default
+.BR Linux-PAM
+environment variables should be set and also
+.BR initgroups "(2) "
+(or equivalent) should have been performed.
+
+.SH "VALID FLAGS"

+
+.SH "RETURN VALUE"
