Mounting on the cluster will be handled by biacmountd. The user communicates with this daemon using the biacmount/biacumount commands. biacmountd processes requests for mounts by validating a user's access to an experiment from users.txt database. On successful validation, it extracts the user's password, using a shared key, from an encrypted file (restricted access) and mounts the requested experiment. Return values indicate mount status.
