8570: Incoming parameters:
8571: 1. domain

8573: status types (e.g., faculty, staff, student etc.)

8575: If the institutional status string in undefined, the domain
8576: default quota will be returned.

8578: Returns:
8579: 1. Default disk quota (in Mb) for user portfolios in the domain.
1.536 raeburn 8580: 2. (Optional) institutional type which determined the value of the
8581: default quota.
1.472 raeburn 8582:
8583: If a value has been stored in the domain's configuration db,
8584: it will return that, otherwise it returns 20 (for backwards
8585: compatibility with domains which have not set up a configuration
8586: db file; the original statically defined portfolio quota was 20 Mb).
8587:
1.536 raeburn 8588: If the user's status includes multiple types (e.g., staff and student),
8589: the largest default quota which applies to the user determines the
8590: default quota returned.
