NSE4 FortiGate Security 7.2 LDAP authentication failure, what's wrong?

NSE4 FortiGate Security 7.2, Lab04,  Exercise 1,  Authentication cannot contact the LDAP server

In the 1st section of the Lab Guide (Configure an LDAP Server on FortiGate), the student is asked to configure LDAP:

But when testing the connectivity, it says ‘Can’t contact LDAP server’:

This is because the student needs to use the complete username "uid=adadmin,cn=Users,dc=trainingAD,dc=training,dc=lab" in the ‘Username’ box as mentioned in the document, not just "adadmin" or else…

When entering in:

uid=adadmin,cn=Users,dc=trainingAD,dc=training,dc=lab   as the username and

Training!                     as the password, the connection test will be fine.
