No Active Directory label in User Management

Hi Everyones!

I have strange problem. After install Freepbx (asterisk 14) on Debian 9 (due to powerpbx instruction) unfortunatelly i cant put link :expressionless:

In User Management Module I have not label ā€œAuthentication settingsā€ and I cant chose Active Directory to synchronize my users. How I can install this or what I need to do for enable this option?

I must sign that Iā€™am very begginer :slight_smile:
