https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/...
states 80 and 443 as well as 389 and 636 - despite the use of StartTLS.
So which ports in the list could probably be omitted? (if we do not need
Kerberos functionality in that particular setup)
Kerberos is needed for users to be able to log in with their passwords:
sssd authenticates users by obtaining a TGT using their credentials.
Kerberos is also needed to look up user/group information: sssd uses the
host's identity to authenticate to the IPA LDAP server.
You could try configuring your clients to use the IPA-provided KDC
proxy; Kerberos traffic would then go via https.
