Integrated DNS is not mandatory at all. Without IPA DNS you have
to manage all IPA system records manually on external DNS



if i understood correctly from the documentation , integrated DNS
is mandatory for configuring AD trust. is that correct ?

No, it is not needed for AD trust, you need to add additional DNS
records



Can the integrated DNS be configured as forward only ? Do the
clients need to have IPA DNS as a resolver or they can just use
existing DNS server ?

You don't need to install IPA DNS.

All records the IPA needs can be received from command `ipa
dns-update-system-records --dry-run` (IPA4.4+)


there are some SRV records (_kerberos, _kpasswd, _ldap, _ntp) reported 
by the above command which would not be easy to add them to existing 
DNS (DNS updates are form based and they allow only A and CNAME 
records). When and by whom are those records used and what is the 
consequence of not adding them  into existing DNS ?




These are mainly used by ipa-clients (SSSD) with dynamic configuration. 
However you may configure client to use static configuration (without 
auto detection of working IPA servers) and it should work. However I'm 
not sure about DNS records required for AD Trust, who is the consumer, 
if only SSSD or not.

No, integrated dns is an optional component of ipa,  even for ad integration. 


But without integrated DNS, you have to correctly configure all srv records by 
manual.
