[Samba] After the classicupgrade from samba3 to sernet-samba-4.2.1 , users are not able to remote desktop anymore ( bug11061 )

Hello Mario.. 

first.. sernet has samba 4.2.2 release. 

i suspect these settings are for the RDP.. 
>        server services = -winbindd +winbind
>        auth methods = winbind, sam
but if u use it like about, remove the auth mehods line. 

samba 4.2 with 4.1 winbind beheavor, and a working rdp. : 
+        server services = -winbindd +winbind ( and the defaults, see below ) 

samba 4.2 winbindd with winbind like member server behaivor, and a working rdp :
         server services = -dns ( and the defaults, see below ) 
+        auth methods = winbind, sam

this is against the defaults of samba. 

samba-tool testparm -vv | grep "server services" 
( the default of my samba 4.2 installation, with bind9 ) 
server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd,
ntp_signd, kcc, dnsupdate


Greetz, 

Louis
