Revision as of 18:45, 23 December 2008

An interactive 'ndpfuseradd' script is now available from SVN and is installed (via RPMs) in /usr/local/sbin/ on selected machines (hooimijt, vlaai, stal), but can be installed anywhere if you like.

Prerequisites for using this tool:

  • you must have your ssh key in an agent, and you must be able to login as root via ssh on the file server hosting the end-user home directories
  • you must be in the list of LDAP managers hard-coded in the tool
  • the tool (and the RPM dependencies) require perl-LDAP, perl-IO-Socket-SSL, perl-Net-SSLeay, and the 'dialog' command

Then start the tool - it's fully interactive. First select the (unix) group you want to add the new user to, and then complete his personal details. Have the new user's SSH key handy and it will be automatically inserted as well. It's simple now: 

/usr/local/sbin/ndpfuser

Just before committing the new entries to LDAP and the NFS server, you'll get to review the new entries. If you don't like them, press ESC twice to exit (actually, that will exit at any dialog box), and you're in the clear. Also, some basic sanity checks are built in, but you can likely break the tool if you want to.


Sources

In subversion: 

 https://ndpfsvn.nikhef.nl/repos/pdpsoft/trunk/nl.nikhef.ndpf.tools/ndpfuseradd/

and the RPMs are at 

 http://stal.nikhef.nl/mirror/nikhef/ndpfuseradd-1.0-1.noarch.rpm


I tried extracting the list of managers automatically, but after having secured the LDAP server so that anonymous users can no longer glance such information with a single ldapsearch, I found myself in a catch22 situation (you need to bind to directory in order to see who you can bind as ...). Too bad, but I agree it still needs a configuration file instead of a hard coded list in the script. Will work on this.
