If you're a power user, handy with Google and reading software documentation, you're welcome to take a look at Configuring Kerberos for the UMBC realm. In other news, the GL systems do allow GSSAPI authentication. You can install PuTTy on OS X with Homebrew: brew install putty -with-gtk+ And then run it from terminal as putty.
In a typical SSH public key authentication setup, the keys that are allowed to authenticate for a user are listed in a file in their home directory which-in our setup-the SSH process doesn't have access to until you've already authenticated to Kerberos. AFS uses your Kerberos credentials to grant access to your home directory during the login process. The GL servers use a secure network authentication protocol called Kerberos for logins, and home directories are served from a network filesystem called AFS. We understand that might be frustrating to some of our more security-minded students, so here's why: Sorry, but given the nature of our infrastructure, the GL servers do not support SSH public key authentication for normal users.
