Why does Sid to name translation not work?
SID to name translation can be effected if SMB signing is required on one side, but not enabled on the other. Since we have an external domain trust, NTLM authentication is used. It is possible that this configuration mismatch will block SID to name translation.
Where can I find the Sid policy policy?
You will find this policy in Computer Configuration->Windows Settings->Security Settings->Local Policies->Security Options . It should be noted that by enabling this policy, domain controllers will allow translations to occur even if the user is anonymous or sends bad credentials.

Where does the local security identifier ( SID ) come from?
The operating system generates a SID that identifies a particular account or group at the time the account or group is created. The SID for a local account or group is generated by the Local Security Authority (LSA) on the computer, and it is stored with other account information in a secure area of the registry.
When do security authorities use the same Sid twice?
SIDs always remain unique. Security authorities never issue the same SID twice, and they never reuse SIDs for deleted accounts. For example, if a user with a user account in a Windows domain leaves her job, an administrator deletes her Active Directory account, including the SID that identifies the account.
What does it mean when a SID is unique to one domain?
This means that the SID for an account or group that is created in one domain will never match the SID for an account or group created in any other domain in the enterprise. SIDs always remain unique.
