Summary0000806: LDAP plugin fails backup of 2012R2 Active Directory with Fatal error: no type in startBackupFile packet
DescriptionI have successfully setup the LDAP plugin to backup an MS 2012R2 Active Directory according the example configuration file.
The LDAP bind user is a member of the "Domain admins" and "Backup operators" AD groups.

The backup job processes 1858 objects after which it fails with the following error:

JobId 589: Fatal error: fd_plugins.c:722 Command plugin "python:module_path=/usr/lib64/bareos/plugins:module_name=bareos-fd-ldap:uri=ldap\://XXX.ultra-d.local:basedn=dc=ultra-d,dc=local:bind_dn=cn=backupuser,cn=Users,dc=ultra-d,dc=local:password=XXX": no type in startBackupFile packet.

Restarting the job results in the same issue after the exact same amount of processed objects.
It seems that the plugin is choking on a specific ldap object but the debug information does not provide me any hints about the issue of a specific object. I also don't have any reason to doubt that I have a problem with ldap objects in my Active Directory since that seems to be working all just fine.

If I narrow down the backup to a specific OU that does not seem to contain "problem objects" the backup finishes successful.

I would love to debug this issue further on my specific "problem objects" but since the file daemon debug output does not really provide usable information I have no idea how to debug this issue any further.

I suspect that certain attribute or attribute values are a problem for the LDAP plugin.

Besides fixing the issue that also these objects can be processed successfully it would be nice if "problem" objects would be identified and reported in the joblog.

The issue also occurs with Bareos 16.2.4
Steps To ReproduceRun a LDAP backup of Windows 2012R2 Active Directory using:
Plugin = "python:module_path=/usr/lib64/bareos/plugins:module_name=bareos-fd-ldap:uri=ldap\\://ldapserver.ultra-d.local:basedn=dc=ultra-d,dc=local:bind_dn=cn=backupuser,cn=Users,dc=ultra-d,dc=local:password=XXX"

Using my AD the issue is 100% reproducible but since it seems to choke on specific ldap objects or attributes I'm afraid that it won't be reproducible on any 2012R2 Active Directory.
