Hello Andrey,

If I understand correctly, IPA manages mydomain.com zone, so adding 
CNAME record should be simple:

ipa dnsrecord-add mydomain.com webserver 
--cname-rec='webserver-1234567890.us-west-2.elb.amazonaws.com.'   # <-- 
do not forget to add dot at the end

If mydomain.com is managed outside IPA, the CNAME should be set on that 
external server, IPA cannot help in this case.
