Subject Re: [DISCUSS] Major business logic refactoring: Move from Account to UserAccount
Date Fri, 14 Nov 2014 18:39:40 GMT
Can a username like "mike" be re-used in multiple accounts?

For example:

Acct1\mike
Acct2\mike

If so, the name "mike" would be insufficient to determine ownership of the
resource in some situations (unless it was fully qualified with its
account).
