 ====== User Account Handling ======
-As there is more than one server that will make up the Wormnet universe, in addition to a few xDSL joined NASes and systems, we need to roll out some kind of central user management database.  Naturally we opted for LDAP.
-The packages required to be installed to do this are:
+===== Creating an Account =====
-  * [[http://packages.debian.org/slapd|slapd]]
-  * [[http://packages.debian.org/nslcd|nslcd]]

-  objectClass: ldapPublicKey
+If you make the users account use the shell ''/usr/bin/rssh'' and edit ''/etc/rssh.conf'' then you can create accounts that can only upload/download files rather than have a full shell - although you will still need to add them to the 'wormnet-shell' group.
