coredump sernet samba 4.1.3

while usage at smb.conf 

 auth methods = guest sam winbind


symtoms :

- SAMBA4 stop clean working
- create coredumps at every client, allmost every second ..
- smbclient -L \\<server> -U Administrator stop working local and remote

samba docus don´t say  that set the allowed auth methods isn´t possible with in AD SERVER or MEMBER mode.

reason for set it : ldap clients ( php/perl/..)

Issue checked and reproducable with sernet samba4.1.x
 + bind 9.8.2( without spnego)
 as well with 9.9.5( with spnego )
