Much of the data in the schema comes from the Rutgers People Database (PDB). That data is normally updated nightly or weekly. However some data -- particularly information required for authentication -- comes from campus systems. That data is fetched every 15 min from the 8 campus systems to a central server.
Currently LDAP does a full rebuild of its data between 6 and 6:30am.
That should bring it into synchronization with both the PDB and the campus systems.
In addition, some data is updated every 15 minutes. Those updates currently include the
information needed to authenticate. Note that the 15 min update may change the DN associated with a
user. Before creating a NetID, users have DN's of the form uid=iid.IID. Once they have a NetID, the
DN is renamed to uid=NETID,....
At some future time, the 15 minute updates will also include email addresses. The rest of the data doesn't make sense to update every 15 min, since the underlying sources are updated at most once a day.
If you maintain a service that uses LDAP for authentication, you should tell your users that it may take up to 30 minutes for a user to become active after creating a new account. In fact the times should range from 11 to 26 minutes, depending upon when the account is activated.
