Whilst this is more of a policy change than a feature update to the tool, and hence probably appropriate for consideration at the <a href=\"http:\/\/www.ict.ox.ac.uk\/oxford\/network\/nag\/\" target=\"_blank\">Network Advisory Group<\/a> (NAG), I thought some explanation here would be appreciated. I&#8217;ll certainly take this item to the next meeting of NAG for discussion.<\/p>\n<p>You can create accounts in <strong>two<\/strong> ways: either one-at-a-time within an <em>existing group<\/em>, or in bulk at the same time as creating a <em>new group<\/em>. The subtlety comes in that these two methods of account creation have, quite deliberately, different maximum lifetime limits. Individual accounts have a 14 day limit and bulk created accounts inherit the lifetime of their parent group, which can be up to 92 days.<\/p>\n<p>So the quick answer to the comments is that yes, you can already create accounts with a lifetime of up to a term, but they must be created along with a new group. As groups and accounts are &#8220;cheap and disposable&#8221; we see no problem in you using this as a way to achieve what you want. Admittedly you have less control over the data on bulk created accounts &#8211; the visitor&#8217;s name and so on &#8211; but we will address that in the updates mentioned in my previous post.<\/p>\n<p>But there&#8217;s more: on the group setup page is a field named &#8220;<em>valid for X consecutive days<\/em>&#8220;, for use with bulk account creation. This allows you to set a start and end time for the group\/accounts which becomes a window of opportunity, within which the account can be used for X days since first log-in. So let&#8217;s say you create a group of 50 accounts with a lifetime of 92 days, but set them to have 21 consecutive days validity. You can give the accounts to visitors and they have a lifetime of only three weeks from first use, but you need only create that group once a term.<\/p>\n<p>Why the different maximum lifetimes, then? Well, it&#8217;s not random and we did consider carefully how the service would be used, and potentially abused; remember that we need to maintain accountability at all times as to who is accessing the network. One concern is that accounts with a long lifetime will either be traded between users, or have the credentials disposed of and subsequently recovered and used by a 3rd party.<\/p>\n<p>If you know, for example with summer school attendees, that they are here for a few months, then you can create a group of accounts with an extended lifetime. But for the majority of cases the visitor will be short-term and single account creation is adequate. Remember also that it&#8217;s often non-IT staff issuing accounts via delegated access to the tool, so we need to moderate their actions in a way which might not be necessary for an IT Officer -only tool.<\/p>\n<p>I think the above answers the questions raised, but if you still feel strongly, please do let me know either by email to <a href=\"mailto:networks@oucs.ox.ac.uk\">networks@oucs.ox.ac.uk<\/a> or in a comment below. If you do, it would be useful to have an example of your use case &#8211; possibly we can tweak things to accommodate your scenario whilst continuing to safeguard access to the JANET network.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Several comments on my recent post about updates to the Visitor Network Account Management tool requested an increase of the maximum account lifetime.
