SSH - GSSAPI settings

It's been awhile since I have posted, things have been going good :)
A weird issue that has come out of nowhere though, and we had to resolve by disabling GSSAPI on the SSH server. However since there are many other servers that could potentially cause the same connection issue I'm wondering if there is a place to disable GSSAPI within RDM?
What seems to happen when connecting via SSH VPN it seems to halt with a GSSAPI message (I don't see this anymore since we disabled it on the server) and the auth takes so long the connection fails.
I can open putty separately and disable GSSAPI and it works immediately, however this doesn't seem to have any affect on RDM SSH VPN connections.
