Unable to set password policy. mac server

Ref - Ver 5.6 (17S2102) Mac server

When I set the password policy for local network users all user details and password are lost the users details plus groups have no information. your not able to access your mac book via the network or change your password.

So we try to restore the OD info but this fails and we are still unable to access the MacBook or network, unless the mac server is stopped then users are able to access there mac book's.

So to fix this issue I have to remove OD, and start again and deploy OD and restore OD then we're able to access our MacBook's. So no password policy is enabled on the local network.

I've DNS, OD, groups, users and profile manager enabled.
