You can remove these lines from your smb.conf, they have no effect with 
the winbind backends you are using:

idmap config * : schema_mode = rfc2307
idmap config MERCURIA : schema_mode = rfc2307

You are shooting yourself in the foot, not only do you have 'winbind 
enum' lines (which you definitely do not require), you also have 
'winbind expand groups = 10', this will work poor old winbind to death 
😁 I suggest you remove those lines.
