If you are going to be running the acedb server a lot, it is better to
run it under the "acedb" account than under your personal login.  The
reason for this is that bugs in the acedb server code may
inadvertently expose your personal files to snooping or deletion if
the server is running under your personal ID.

To run the server as acedb, you must make its database files writable
by the acedb user.  To do this, become the root user, and run the
following commands:

  # chown -R acedb ~acedb/elegans/database
  # chgrp -R acedb ~acedb/elegans/database
  # chmod -R +rw ~acedb/elegans/database

Replace the path ~acedb/elegans with the path to the database that you
want to be accessible.  What this is doing is to make the "database"
subdirectory owned by the acedb user and writable by it.

Still running as root, become the acedb user:

  # su acedb
