Please backport to samba 4.15.x commit e556b4067e0c4036e20fc26523e3b4d6d5c6be42 delivering this fix: With glibc 2.34 we are not able to talk to the DNS server via socket_wrapper anymore. The res_* symbols have been moved from libresolv to libc. We are not able to intercept any traffic inside of libc.
