Attempting to create a one-way trust from freeIPA to AD. Both are fresh installations and
up to date. ADDS on 2k19 and FreeIPA on CentOS 7.
After running `ipa-adtrust-install` running 'smbclient -L
ipaserver.ipa.example.net
-k' only returns `Reconnecting with SMB1 for workgroup listing.`
The error I receive when running `ipa trust-add` is `ipa: ERROR: an internal error has
occurred`. At this point the trust appears in the incoming trusts in AD.
Both firewalls disabled. Both realms have integrated dns and conditional forwarders set
up. All SRV records are resolvable in both directions. I manually created
`_kerberos._udp.dc._msdcs.ad.example.com.` as it was not present.
