7599: 1. Default disk quota (in Mb) for user portfolios in the domain.
7600: 2. (Optional) institutional type which determined the value of the
7601: default quota.
7602:
7603: If a value has been stored in the domain's configuration db,
7604: it will return that, otherwise it returns 20 (for backwards
7605: compatibility with domains which have not set up a configuration
7606: db file; the original statically defined portfolio quota was 20 Mb).
7607:
7608: If the user's status includes multiple types (e.g., staff and student),
7609: the largest default quota which applies to the user determines the
7610: default quota returned.
