Comment 0 for bug 1319320

When trying to join a domain using realmd, this is displayed:

sysoperator@mem4:~$ realm join --verbose test2dc.mdom.com
 * Resolving: _ldap._tcp.test2dc.mdom.com
 * Performing LDAP DSE lookup on: 192.168.15.23
 ! Received invalid or unsupported Netlogon data from server
realm: Cannot join this realm

This problem is well know and it has been fixed in Samba 4.1.7. Unfortunately, the samba version provided by apt is 4.1.6

This problem also surface when using SSSD, here's an extract of SSSD log file:
