[Freeipa-users] Autentification in application with freeipa

Hi. I asked about Owncloud, Zimbra, etc autentification in freeipa with AD trust. I was offered to use SAML. But I dont undestand SAML. It very dificult for me. I only want use LDAP for autentification as in this artikle https://www.freeipa.org/page/Owncloud_Authentication_against_FreeIPA Or this https://www.freeipa.org/page/Zimbra_Collaboration_Server_7.2_Authentication_...

Articles work fine but only for freeipa users. It dont work for AD users from trusted domain.

I found Red Hat documentation for sinchronising AD with IPA https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm...

If i do it i can see AD user in ldap requests for ipa server?
