Review server tests

[psi29a]

Some tests, on the server side, require an ordered response but this is not guaranteed. We do some manual re-ordering on the server side to meet the requirements of the test case. LDAP doesn't care what order the 'bag of attributes' comes in so we shouldn't care either. We'll have to re-write our tests do checking of elements them selves instead of getting the str representation and comparing those.
