I have set up a 32-bit RHEL 6.3 VM as an identity management server, including 
bind-dyndb-ldap-1.1.0-0.9.b1.el6_3.1.i686.

The server responds correctly to simple SRV queries:

[root@ipa ~]# dig @localhost _ntp._udp.rhev.icp.selfip.net srv

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.5 <<>> @localhost _ntp._udp.rhev.icp.selfip.net srv
; (2 servers found)

During a zone transfer, however, the SRV records are "truncated"; only the short hostname is sent, rather than the FQDN:

[root@asterisk ~]# dig @ipa.rhev.icp.selfip.net rhev.icp.selfip.net axfr
