Due to conflicting technologies and binaries available at the RCF, it is necessary to properly configure your environment in order to benefit from the Kerberos 5 infrastructure at the RCF.

The most important issue with respect to your environment is your PATH environment variable. To see the current value of your PATH variable use the command echo $PATH. To pick up the correct binaries, it is important that you have the following three directories in your path and in the correct order:

1. /usr/afsws/bin
2. /usr/bin
3. /usr/kerberos/bin

The order of these directories in your PATH variable is important because there are conflicting AFS and Kerberos 5 binaries that exist on the systems. This order will increase the probability that you are picking up the correct binaries.

Ssh Agent and Ssh Keys

In order to take advantage of the Kerberos TGT passing functionality and automatic AFS token grabbing, it is necessary for you to remove all Ssh public/private key and ssh-agent functionality for moving between RCF systems from your environment. (If you don't know what this is then you have not set it up and you can ignore this paragraph).
