Lost AD Connection after updating to 6.5.0 on Readynas 516 #26926627
Hello,
after updating my Readynas 516 from firmware 6.5.0-T338 to 6.5.0 final release, I am getting 'Failed to sync ADS account information for the realm' messages.
In the past, there was no issue regarding AD integration and even the import of the AD accounts worked without any problems.
At the moment, the device is unable to import any AD accounts while account caching is enabled. If account chaching is disabled, I am able to see the AD users in the accounts overview on the device.
Unfortunately, even if the AD accounts are visible (with account chaching disabled), the home folders are not accessible from windows. Even a domain admin can't access the folders or update the security settings.
I already tried rejoining the AD, checked NTP-settings regarding timing issues and tried a rollback to 6.5.0-T338 without any luck.
How can I fix this issue?
Best regards
Dirk
DirkG, please don't run beta 6.5.0 firmware anymore. We are very limited in what we can do to help if you stay on that here and support won't be able to help with that firmware. Please update back to the 6.5.0 production release and open a support case, attach your logs to that case and let us know the case number. Thanks.
When users encounter this issue and do things to try to fix it themselves we lose the ability to get information that would help with identifying the root cause of the issue (so it's much harder to try to find a common cause that could lead to a fix in a future firmware release if that's needed).

Hello DirkG,
What is the OS of the computer that you are using to access the folders/shares? Are you able to access these shares when the authentication is set to local users?
These shares by the way should be set to Everyone and the share permissions should be set by DC.

I am also having the same issue since upgrading to 6.5.0 on my 3130.
Error message in the log is: Account: Failed to sync ADS account information for the realm
All ADS user and group info is gone, users unable to connect to shared folders. Tested my domain and all controllers check ok.. The issue is with the ReadyNAS...
Hello stevecr25,
I think you are already in contact with one of who can remote in to your NAS. Please continue with it as he is one of the higher tier who can probably take a look and help resolve this.

Hello JennC,
I am using systems running Windows 10 Pro, Windows 2008 R2 Server and Windows 2012 R2 Server to access the folders/shares.
With all systems, I am having the same problems.
From my point of view, the problem is related with the error message that the Readynas is not able to import the AD accounts since the update to the final version of 6.5.0. Therefore, ist seems that the users couldn't be authentificated via the Readynas.
Moreover, I am not able to set any permissions for the AD user folders, which are automatically created by the Readynas:
- Via the administrative web page, there is no possibility to define any acces rights, if the folders belong to AD users
- Via SMB, I am not able to connect to this folder, because the access is denied (Unable to import AD accounts...)
Please also have in mind that once the AD account caching is disabled (direct query of the accounts to to DC), the problem disappears and there was no problem at all with all other OS versions of the Readynas 516 before.
Therefore, it is not a problem of the share permissions, but with the security handling of AD accounts within the Readynas.
Best regards

Hello JennC,
please be aware, that there are more users with the same problem:
https://community.netgear.com/t5/ReadyNAS-in-Business/AD-DC-Import-Error/m-p/1091108#M4881
Moreover, I have already sent my logs.
In additon some observations:
- There was no problem with 6.5.0-T338
- The problem appeared after updating from 6.5.0-T338 to 6.5.0 final
- Downgrading from 6.5.0 final to 6.5.0-T338 has not restored the working conditon
- You can access folders after disabling AD caching on the Readynas and logoff/logon on your windows machine, but not the automatically created UserFolders, which already exists
- You have access to UserFolders, which are created automatically after the switch to 6.5.0 final
From my point of view, there was something mixed up with the management of the SID from the AD within the Readynas while upgrading to 6.5.0 final.
