Old (old) style configuration keys all started with DEFAULT_ but
|
|
|
304803 |
the configuration entry lookup requires the has of the lower case
|
|
|
304803 |
name. So trying to these old style names failes because thet don't
|
|
|
304803 |
has to the same value.
|
|
|
304803 |
|
|
|
304803 |
So change the key lookup to strip the DEFAULT_ string and retry
|
|
|
304803 |
the lookup so valid entries hash properly.
