Manual/LDAP account login.
Do not use Manual/LDAP account login unless you have been specifically advised to.
In particular students should NEVER use Manual/LDAP account login.
If you use this login method you may temporarily be able to login, but it will create a duplicate account for you that is separate from your normal account and will not be maintained. You will not have access to your contents, and will stop working entirely shortly.
All students should login using the "Login with Microsoft 365" option.
External examiners are the only ones currently who are being advised to log in using Manual/LDAP account login.
