null not registered with TOTP </amLogEntry>

Cause
User Store was the Active Directory Lightweight Directory Services. The sAMAccountName attribute was hidden. CN was used instead of sAMAccountName attribute.

Resolution
TOTP needs the value of the sAMAccountName attribute. Also, the AD-LDS must replicate the value of the sAMAccountName attribute from the AD.
