1.536 raeburn 7275: Retrieves default quota assigned for storage of user portfolio files,
7276: given an (optional) user's institutional status.
1.472 raeburn 7277:
7278: Incoming parameters:
7279: 1. domain
1.536 raeburn 7280: 2. (Optional) institutional status(es). This is a : separated list of
7281: status types (e.g., faculty, staff, student etc.)
7282: which apply to the user for whom the default is being retrieved.
7283: If the institutional status string in undefined, the domain
7284: default quota will be returned.
1.472 raeburn 7285:
7286: Returns:
7287: 1. Default disk quota (in Mb) for user portfolios in the domain.
1.536 raeburn 7288: 2. (Optional) institutional type which determined the value of the
7289: default quota.
1.472 raeburn 7290:
7291: If a value has been stored in the domain's configuration db,
7292: it will return that, otherwise it returns 20 (for backwards
7293: compatibility with domains which have not set up a configuration
7294: db file; the original statically defined portfolio quota was 20 Mb).
7295:
1.536 raeburn 7296: If the user's status includes multiple types (e.g., staff and student),
7297: the largest default quota which applies to the user determines the
7298: default quota returned.
