Hi
I have completed changed the scenario and I managed to install freeipa-server 4.1 (Somebody publish the right repo for Centos and it worked really well)

Yes, sorry, that was a typo.
So, starting again from scratch, new machine, the whole installation process went well, not issues there but:
* FreeIPA is supposed to generate a PassSync user by running ipa-replica-manage *--winsync **--passsync*=/PASSSYNC_PWD. (See also man ipa-replica-manage).
I tried 5 times, the user was never created on the ipa server, I had to create it manually (I gave it admin permissions so it could create/delete/update users). Doing that, the password sync worked all right. We submit a password reset in AD and that propagated all right, tested and it worked fine. 
/
* In one scenario I uninstalled freeipa (still kept the packages), installed again and something went wrong with the kerberos keys. After creating the AD --> LDAP certs and successfully syncing the passwords, I could read in the /var/log/messages a password decryption issue (kerberos related) everytime I tried to log as any user. I have tried uninstalling freeipa and also uninstalling removing the product completely and re-installing. it did not matter if I tried to rebuild the kerberos keys, the issue was always there, so I have to start afresh with a new box. 



Something is really messed up with the system.
Do you have some kind of backup and restore running in the background?
It seems that for some reason a kerberos (probably master) key was rewritten in some way. 



So.. that has been all so far

Thanks

Gonzalo

Hello, Gonzalo,

Any progress on your Password Synchronization?

You can find the doc on PassSync here.
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Windows_Integration_Guide/pass-sync.html#windows-pass-sync
The doc is on PassSync 1.1.5, but 1.1.6 remains intact except the default SSL version to connect to the 389 Directory Server (as we discussed before). 

We had a dicussion regarding the PassSync user you had to create:
uid=passsync,cn=users,cn=accounts,dc=corp,dc=company,dc=com
FreeIPA is supposed to generate a PassSync user by running ipa-replica-manage *--winsync **--passsync*=/PASSSYNC_PWD. (See also man ipa-replica-manage)./

Please see the above doc regarding the user creation.

 *
    The username of the system user which Active Directory uses to
    connect to the IdM machine. This account is configured
    automatically when sync is configured on the IdM server. The
    default account is
    |uid=passsync,cn=sysaccounts,cn=etc,dc=example,dc=com|.
 *
    The password set in the |--passsync| option when the sync
    agreement was created.
I'm sending this response to freeipa-users to share the info and request for more suggestions. 

Thanks,
--noriko

Hi

I had to manually create the user!! For some reason I thought the sync

Since the above bind failed, your PassSync has no right to update the

LDAP_INSUFFICIENT_ACCESS.

  UID: 1481000790

  GID: 1481000790

  Account disabled: False

  the password is still set as False
The PassSync Tool got defined as base search:
cn=users,cn=accounts,dc=corp,dc=company,dc=com .. Which should be all right 

Thanks for all your help!
