Windows; second hop auth delegation; NetApp device

Hello,

Has anyone else encountered problems when using a netapp file storage device in a second hop (with kerberos and auth delegation turned on)?

In one environment we have a NetApp Model: FAS3220, OS: 7 mode v8.2.1 which refuses to let us write to storage via a windows host.

The storage admins tell me its not presenting a username although from the logging I’ve seen I’m not convinced this is the case.

In other environments we have a different NetApp model FAS3220 OS: 7 mode v8.2.1 where it works.

Anyone else found a solution for this (or even a way to debug it)?

Many thanks

Jon
