After my education on what IPA/AD trusts can and can't do, I decided to give the IPA-AD sync option a try. After finally finding what I think is the proper software to install on the AD DC (389-PassSync-1.1.6-x86_64.exe from the Fedora site), I believe I have the settings correct, but the Password Synchronization software refuses to connect. After changing the Log Level option to 1, I get the below in the log file, which doesn't really tell me much of anything.

The credentials are definitely correct and IPA is set up to do LDAPS as, on the same AD server, I can connect and bind using ldp.exe with the same settings/credentials and I'm able to browse the LDAP tree. I've done a wireshark capture and it looks like it's failing in the TLS negotiation. I can see this entry in the capture:
TLSv1 Record Layer: Alert (Level: Fatal, Description: Protocol Version)
Content Type: Alert (21)
Version: TLS 1.2 (0x0303)
Length: 2
Alert Message
Level: Fatal (2)
Description: Protocol Version (70)

What version of 389-ds-base are you using?

# rpm -q 389-ds-base

I added the IPA CA cert to the cert files in the 389 passsynch directory and I can confirm that as below.
C:\Program Files\389 Directory Password Synchronization>certutil -d . -L
Certificate Nickname Trust Attributes
IPA CA cert                                                  CT,,
When I list that specific certificate, I can see the below in the output.
    Certificate Trust Flags:
        SSL Flags:
            Valid CA
            Trusted CA
            Trusted Client CA
        Email Flags:
        Object Signing Flags:
Any pointers/ideas?
