7312: Incoming parameters:
7313: 1. domain
1.536 raeburn 7314: 2. (Optional) institutional status(es). This is a : separated list of
7315: status types (e.g., faculty, staff, student etc.)

7317: If the institutional status string in undefined, the domain
7318: default quota will be returned.
1.472 raeburn 7319:
7320: Returns:
7321: 1. Default disk quota (in Mb) for user portfolios in the domain.
1.536 raeburn 7322: 2. (Optional) institutional type which determined the value of the
7323: default quota.
1.472 raeburn 7324:
7325: If a value has been stored in the domain's configuration db,
7326: it will return that, otherwise it returns 20 (for backwards
7327: compatibility with domains which have not set up a configuration
7328: db file; the original statically defined portfolio quota was 20 Mb).
7329:
1.536 raeburn 7330: If the user's status includes multiple types (e.g., staff and student),
7331: the largest default quota which applies to the user determines the
7332: default quota returned.
