|
See if the owner domain and name |
|
in the URL match those in the expected environment. If so, return |
|
three element list ($ownername,$ownerdomain,$ownerhome). |
|
|
|
Otherwise return the null string. |
|
|
|
If second argument 'setpriv' is true, it assigns the privileges, |
|
and returns the same three element list, unless the owner has |
|
blocked "ad hoc" Domain Coordinator access to the Author Space, |
|
in which case the null string is returned. |
