Hello Hugh,

Could you tell us the version of 389-ds-base the PassSync is trying to access? If the directory server is not new enough (389-ds-base-*1.3.2.26 <http://www.port389.org/docs/389ds/releases/release-1-3-2-26.html> *or 389-ds-base-<http://www.port389.org/docs/389ds/releases/release-1-3-3-8.html>*1.3.3.8 <http://www.port389.org/docs/389ds/releases/release-1-3-3-8.html>*), could you please try setting the following environment variable on the Windows machine on which PassSync is running?*
<http://www.port389.org/docs/389ds/releases/release-1-3-3-8.html>*

   http://www.port389.org/docs/389ds/releases/release-passsync-1-1-6.html

   PassSync 1.1.6 supports TLS version 1.1 and newer SSL versions
   supported by NSS. SSLv3 is disabled, by default. To force to enable
   SSLv3.0, an environment variable LDAPSSL_ALLOW_OLD_SSL_VERSION has
   to be set with some non NULL value.

   In Computer | Properties | Advanced system settings | Environment
   Variables | System variables, add variable:
   LDAPSSL_ALLOW_OLD_SSL_VERSION, value: 1

Thanks,

Subject:        [Freeipa-users] Passsync fails to connect to LDAP

All,
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.
02/17/15 13:18:20: Backoff time expired.  Attempting sync
02/17/15 13:18:20: Password list has 1 entries
02/17/15 13:18:20: Ldap bind error in Connect
 81: Can't contact LDAP server
02/17/15 13:18:20: Attempting to sync password for ADSERVER$
02/17/15 13:18:20: Searching for (ntuserdomainid=ADSERVER$)
02/17/15 13:18:20: Ldap error in QueryUsername
 81: Can't contact LDAP server
02/17/15 13:18:20: Deferring password change for ADSERVER$
02/17/15 13:18:20: Backing off for 256000ms
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)
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
SSL,S/MIME,JAR/XPI
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?
Thanks in advance,
Hugh
