I'm just going to disable nwam just in case. I won't be using it in my
"production" setup as I will have several VLANs.
I only left it on for now to do these simple tests in VMs.

Both partly stem from LDAP client profile updates moving ldap_client_file before getting an update, and then not being able/willing to move it back again if something goes wrong.
>> However, I think the problem here is - are you storing this LDAP profile in AD? The LDAP client will do a refresh of the config from the profile on the LDAP server - I suspect on boot it's trying to do a refresh, not finding a profile, and the zeroing out ldap_client_file.
