Error Code 8344 KB ID 0001636

Problem

With Azure AD Replication, you may notice that you have the following error when you take a look at your connector status;

Error: permission-issue
Connected data source error code: 8344
Connected data  source error: Insufficient access rights to perform this operation.

Solution: Error Code 8344

Firstly ensure that the user you are running AAD sync under, has the following permissions on the ‘root’ of your local AD domain.

• Replicating Directory Changes: Allow
• Replicating Directory Changes All: Allow

If the problem persists it’s usually because the account that is running the AAD sync does not have the appropriate rights to the mS-DS-ConsitencyGuid attribute for the affected users in the local Active Directory. The following commands will add the appropriate rights you ALL your local users;

$accountName = "Domain-Name\User-Name" 
$ForestDN = "DC=Domain-Name,DC=Domain-Extension"
$cmd = "dsacls '$ForestDN' /I:S /G '`"$accountName`":WP;ms-ds-consistencyGuid;user'"
Invoke-Expression $cmd

Lastly, if you have this problem on some ‘sporadic’ users, check to ensure that their individual user objects and inheritance enabled on their user object, before retrying.

If the problem persists use the AD Connect Troubleshooter.
