I have an implementation of IBM's disk virtualization technology in my environment - SVC (SAN Volume Controller). The device is managed by either GUI or CLI. In order to use CLI, a 1024-bit RSA public key needs to be uploaded for the user to authenticate against.
I am able to authenticate against the SVC cluster using SSH clients like PuTTY and OpenSSH. I am also able to connect to the SVC cluster using Tectia SSH version 4.x. The problem arises when I try authenticating against the cluster using Tectia verison 6.x. I keep getting an error of "Request exec channel error: Operation failed."
When I set debugging to be a bit more verbose, I do see one line that stands out to me:
So, if I'm reading correctly, I do get authenticated okay to the cluster using my private/public key pair. However, the next few lines proceed to disconnect me from the SVC cluster:
Has anyone here tried using Tectia SSH with an IBM SVC cluster and managed to get it to work?

We have some customers that are using 6.x Tectia client against an IBM SVC cluster without problems.
Could this be failing when it tries to open an agent forwarding channel? Does it work if you try connecting with agent forwarding disabled? such as:
Can you post more of the debugging output, specially the lines leading up to the failure and the command line options (if any) that are used for the connection?
