Any ideas on this issue?

I've been troubleshooting this issue.
Reinstalled password sync, certificates , verified those certificates. And the sync started working, the sync user was able to check the remote password.
Today, again, it's back: Binding with the user returns error 53 :(

09/02/16 09:32:12: Attempting to sync password for juankar
09/02/16 09:32:12: Searching for (ntuserdomainid=juankar)
09/02/16 09:32:12: Checking password failed for remote entry: uid=juankar,ou=xxxxx
09/02/16 09:32:12: Deferring password change for juankar

and the ldap server is responding with error 53:

[02/Sep/2016:09:32:12 +0200] conn=36 op=0 BIND dn="uid=juankar,xxxxxxx" method=128 version=3
[02/Sep/2016:09:32:12 +0200] conn=36 op=0 RESULT err=53 tag=97 nentries=0 etime=0

With ldp , from the affected windows 2012 server and connecting to the involved ldap server, using ssl I get no errors at all:

res = ldap_simple_bind_s(ld, 'uid=juankar,xxxxxx', <unavailable>); // v.3
Authenticated as: 'uid=juankar,ou=sistemas,ou=eprinsa,ou=usuarios,dc=metaeprinsa,dc=org'.

Going crazy.

Thank you both for your answers.
Sorry I should've included more lines in my log.
Bindings with the passSync user are ok. But after that, the system tries to bind with the user whose password is being changed and that's when it fails:

This is what happens when user jmml01 changes his password in Windows and he was connected to the failing controller:

08/30/16 08:28:56: Searching for (ntuserdomainid=jmml01)

However if the user was connected on the other controller, the password will be successfully changed. I also believe it's a certificate problem , I'm going to review my config on that side.

Hi, 389ds'ers,

I have two 2012 r2 domain controllers with passsync 1.6 x64 installed. They're both targeting 389-ds-base- . They're working flawlessly.
I dont know if it's been a software update or a change in the domain settings. Thing is today, one of the controllers has stopped sync'ing.
Could there be a certificate issue?  Did you have any chance to check the cert with the tool certutil?

Also, if you could try binding as the user "uid=juankar,ou=xxx...." using an ldap command over SSL, you may be able to get more info, e.g., returned from the server.

Whenever I change one password in that controller, the following message is logged in passsync.log:

08/29/16 11:30:07: Password list has 1 entries
08/29/16 11:30:07: Attempting to sync password for juankar
08/29/16 11:30:07: Searching for (ntuserdomainid=juankar)
08/29/16 11:30:07: Checking password failed for remote entry: uid=juankar,ou=xxx....
08/29/16 11:30:07: Deferring password change for juankar

and in the server access log I get ldap bind err=53 when the passsync user tries to check the password:

[29/Aug/2016:11:30:07 +0200] conn=276 fd=67 slot=67 SSL connection from xxxx

[29/Aug/2016:11:30:07 +0200] conn=275 op=2 UNBIND

Any hints? Could be a problem with certificates? They're both using the same CA (windows CA Cert serv is installed in one of the DCs)
