Unit Test the CIS login

[OhmGeek]

Unit tests have now been written for the basic CIS auth.

TODO:

• Get CIS to give us two test accounts: one associated with Aidan's, and one not.
• Write Unit tests

Writing unit tests:

We need to cover several cases:

1. Credentials correct, and they are a member of St Aidan's
2. Credentials correct, but they aren't a member of St Aidan's
3. Credentials are not correct - this should fail.

We also need to make both the username, e.g. abcd12, as well as the full domain work (so with both the long and short versions).
