+Subject: [PATCH] Free verto context later in KDC cleanup
+
+The KDC supplies the verto context to kdcpreauth modules via the loop
+method (added in commit 83b4ecd20e50ad330cd761977d5dadefe30a785b).
+This context should remain valid until kdcpreauth modules are
+unloaded, as modules might refer to it during cleanup.  In particular,
+the OTP module references the verto context when freeing the RADIUS
+client object (commit e89abc2d4ea1fea1ec28d470f297514b828e4842), which
+can cause a memory error during KDC shutdown without this change.
