The Directory team have requested that we allow token login to the
Directory, where a user uses LSAAI credentials to obtain a token from
the Directory, and then uses this to authenticate Directory sync. This
has been implemented via an environment variable, in an analogous way to
the already existing username/password method.
The default start time for the Directory sync has been shifted to 22:30,
to prevent conflicts with the Bridgehead auto-update.
Relevant changes have been made to the documentation.
There were problems with the passing of environment variables from
bbmri.conf to the Directory synce container:
* The Directory password variable was misspellt.
* Some useful variables were missing.
Additionally, a delay was added before launching Directory sync,
to give Blaze time to start up.
