If this is your first time logging into any CCR server or web portal, you will get this error when logging into OnDemand:


Error - - home directory '/user/your_username'    does not exist for user:  your_username


As seen in this screenshot:



Users MUST login to a CCR front end server at least one time before trying to use OnDemand.  


Instructions for how to do so can be found here


During this first login, your home directory will be created.  You will also be directed to run a script to create SSH keys needed to run jobs on the clusters:


Welcome, this is your first login.  Please run this script before attempting to run any jobs on the cluster: /util/ccr/bin/ssh_no_password.sh


Users should copy and paste this into the command line:


/util/ccr/bin/ssh_no_password.sh


You may then log out and go back to using the OnDemand portal.
