Missing instructions L09 E4 T4.1

[miberr]

Lab 9, exercise 4 task 4.1 is missing instructions on logging in with different credentials. This should be fixed:

• Add instructions to open an InPrivate -tab
• Log in with Azure credentials (different from tenant credentials, at least on GoDeploy)
• Note to fix the clock in VM since Azure portal is very sensitive about incorrect time (had many of these issues)

In addition all further instructions need to be modified to include instructions for switching browser instances.
