7662: Incoming parameters:
7663: 1. domain
1.536 raeburn 7664: 2. (Optional) institutional status(es). This is a : separated list of
7665: status types (e.g., faculty, staff, student etc.)
7666: which apply to the user for whom the default is being retrieved.
7667: If the institutional status string in undefined, the domain
7668: default quota will be returned.
1.472 raeburn 7669:
7670: Returns:
7671: 1. Default disk quota (in Mb) for user portfolios in the domain.
1.536 raeburn 7672: 2. (Optional) institutional type which determined the value of the
7673: default quota.
1.472 raeburn 7674:
7675: If a value has been stored in the domain's configuration db,
7676: it will return that, otherwise it returns 20 (for backwards
7677: compatibility with domains which have not set up a configuration
7678: db file; the original statically defined portfolio quota was 20 Mb).
7679:
1.536 raeburn 7680: If the user's status includes multiple types (e.g., staff and student),
7681: the largest default quota which applies to the user determines the
7682: default quota returned.
