6436: Incoming parameters:
6437: 1. domain
1.536 raeburn 6438: 2. (Optional) institutional status(es). This is a : separated list of
6439: status types (e.g., faculty, staff, student etc.)

6441: If the institutional status string in undefined, the domain
6442: default quota will be returned.

6444: Returns:
6445: 1. Default disk quota (in Mb) for user portfolios in the domain.
1.536 raeburn 6446: 2. (Optional) institutional type which determined the value of the
6447: default quota.
1.472 raeburn 6448:
6449: If a value has been stored in the domain's configuration db,
6450: it will return that, otherwise it returns 20 (for backwards
6451: compatibility with domains which have not set up a configuration
6452: db file; the original statically defined portfolio quota was 20 Mb).
6453:
1.536 raeburn 6454: If the user's status includes multiple types (e.g., staff and student),
6455: the largest default quota which applies to the user determines the
6456: default quota returned.
