Can't connect to AD.

Hello, I've currently some problems to connect to the AD. When I test the username there is an error.
My domain otp.test
The AD server is serverad
and the account for synchronisation is sync

The Base DN is DC=serverad,DC=otp,DC=test
the Bind DN CN=sync,CN=Users,DC=otp,DC=test
with the correct password.

What did I do wrong.

Thanks in advance for your help.
