[Samba] Samba firts DC fail over

[Keshia lesly diana Etsiké malam]

Hello,
I am currently testing for Samba4. The creation of the domain and the secondary Dc implementation works well. But by performing tests for a fail over situation I realized that when the DC that created the domain is in fail over the linux client machine can no longer retrieve the list of users from the domain. I would like to know if a person has already faced this situation and if so how he solved it.

 Thank you.
