The hardcoded values for the home directories for the AD users did
not properly scale up from the POSIX attrs only test scanario.
When using POSIX attrs, the home dir is returned as whatever is set
in the AD (/home/username by default). Without using POSIX attributes,
the /home/domain/username form is taken by default.
Refactor the tests to take this behaviour into account.
