[Building Sakai] adding provided users as local users

[John Bush]

yeah, I've been thinking about this.  The one issue is that the
cache's occur on every app server, so you can use quartz to do this
b/c there isn't a way to get a job to run on every app server in a
reoccurring way.  But I think there are other ways, worth thinking
about some more.  Basically a persistent cache would do it.

Each time sakai calls the provider about a user, your provider would update the entry in the table.  Then if LDAP failed, it would just use the info from that table.  Just an idea.
