+.SH NOTES
+The user session keyring was added to support situations where
+a process doesn't have a session keyring,
+perhaps because it was created via a pathway that didn't involve PAM
+(e.g., perhaps it was a daemon started by
+.BR inetd (8)).
+In such a scenario, the user session keyring acts as a substitute for the
+.BR session-keyring (7).
