Michael Jumper commented on GUACAMOLE-363:
------------------------------------------

While working on the database auth changes related arbitrary storage of 
attributes from other extensions (necessary for GUACAMOLE-96), I noticed that 
some tables were missing indexes relative to the other schema implementations. 
Reorganizing/reformatting the SQL to match the existing MySQL and PostgreSQL 
schema scripts, I found:

* Indexes are missing for the various foreign keys (SQL Server, like 
PostgreSQL, requires that such indexes be created manually).
* {{ON DELETE CASCADE}} and {{ON DELETE SET NULL}} are not always possible due 
to SQL Server's lazy implementation of these, requiring manual implementation 
of those actions with triggers.

I believe I have things working, including the trigger implementations of 
missing {{ON DELETE}} actions, with things reformatted so that things are 
(hopefully) more easily compared between the different implementations of the 
same schema.

Will open a PR once INFRA-15505 (repository rename) is completed.

> Given recent focus on renewing Guacamole compatibility with Windows, having 
> Microsoft SQL Server support seems like a good move.  Also, SQL Server is now 
> available on Linux, since (apparently) Microsoft <3 Linux, so this will 
> provide SQL Server as a backend for those who want to run that.
> Pull Request coming in just a little while.
