CONTAP-396443: SSH to the node is unsuccessful after enabling Cisco DUO
Issue
Customers experience system crashes when using Duo for SSH authentication in conjunction with an authentication proxy that requires credentials.
The issue occurs because the Duo integration mishandles proxy authentication, leading to a crash.
