Hai 

I just looked at the bug report. 
I can say, the  error shown in comment 6, of Francois, that one i have also seen. 
i cant recall what i exactly did. 
i found the logs with the error, i'll put it in the bug report. 
i cant repoduce this, i upgrade to sernet samba 4.2.3. 
ow and the upgrade was because of the windows Printe managment tools, i showed wrong printers + drivers after a rename. 
with 4.2.3 this was gone.  

conf here..  and log below ..  

the config was unchanged. 
[global]
    workgroup = INTERNAL
    security = ADS
    realm = INTERNAL.DOMAIN.TLD

    netbios name = RTD-PRINT1
    domain master = no
    host msdfs = no

    dedicated keytab file = /etc/krb5.keytab
    kerberos method = secrets and keytab
    client signing = if_required

    ## map id's outside to domain to tdb files.
    idmap config *:backend = tdb
    idmap config *:range = 2000-9999

    ## map ids from the domain  the range may not overlap !
    idmap config INTERNAL : backend = ad
    idmap config INTERNAL : schema_mode = rfc2307
    idmap config INTERNAL : range = 10000-3999999

    winbind nss info = rfc2307
    winbind trusted domains only = no
    winbind use default domain = yes
    winbind enum users  = yes
    winbind enum groups = yes
    winbind refresh tickets = yes
    winbind offline logon = yes

    wins server = 192.168.0.1, 192.168.0.2

    usershare path =
    username map = /etc/samba/samba_usermapping

   # For ACL support on member file server
   vfs objects = acl_xattr
   map acl inherit = yes
   store dos attributes = yes

    veto files = /.bash_logout/.bash_profile/.bash_history/.bashrc/
    hide unreadable = yes

    ## Enabling spoolssd
    rpc_server:spoolss = external
    rpc_daemon:spoolssd = fork

    spoolssd:prefork_min_children = 5           # Minimum number of child processes
    spoolssd:prefork_max_children = 25          # Maximum number of child processes
    spoolssd:prefork_spawn_rate = 5             # Start (fork) x new childs if one connection comes in (up to prefork_max_children)
    spoolssd:prefork_max_allowed_clients = 100  # Number of clients, a child process should be responsible for
    spoolssd:prefork_child_min_life = 60        # Minimum lifetime of a child process (60 seconds
                                                # is the minimum, even a lower value has been configured)

---- log...  

and a quick short version :
