[Samba] winbind_krb5_locator usage

[Felix Matouschek]

Hello,
 
I have different Sites in my domain and want the different members to use the respective domain controller of their site.
 
I can't get this to work right. I have a member that is in site B but executing "net ads info" outputs the DC of site A as active.
 
I read about enabling "winbind_krb5_locator", but it is already located in "/usr/lib/x86_64-linux-gnu/krb5/plugins/krb5/".
 
Winbind also does not generate a krb5.conf, even with the option "create krb5 conf" explicitly set to yes.
 
I am using SerNet Samba 4.2.3 as DC and Member.
 
Any suggestions?
 
Greetings,
Felix
