On provision, yes, on a join, no, these records are added at first run
by samba_dnsupdate using 'dns_update_list'. If you look at this file,
you will find at line 16:

${IF_RWDC}SRV          _ldap._tcp.${DNSDOMAIN}                               ${HOSTNAME} 389
${IF_RWDC}SRV          _ldap._tcp.dc._msdcs.${DNSDOMAIN}                     ${HOSTNAME} 389
${IF_RWDC}SRV          _ldap._tcp.${DOMAINGUID}.domains._msdcs.${DNSFOREST}  ${HOSTNAME} 389
