Is there any way to mount a CIFS/SMB file share by authenticating with S4U2Proxy? I need a middleware service to mount a file share and it has a Kerberos ticket from the user who logged into it. I've gotten as far as having a proxy ticket for the file share, but mount.cifs doesn't allow it.
AFAICT from looking at the source code, mount.cifs has no support for S4U2Proxy (i.e., Resource-Based Kerberos Constrained Delegation). Is there any cifs mounting mechanism that supports this?
Edit: The middleware does not have a TGT, only a service ticket.
