Hi Tony,

This works on 8.2.1, not sure if it's changed in 8.3

cluster1::*> diag secd authentication translate -node local -vserver vserver1 -win-name user1

S-1-5-21-3150332139-2813398079-754052488-1110

However if all you want is the SID of an AD user you might consider using the dsquery utility if you have the RSAT tools installed. EG:

C:\>dsquery user forestroot -samid user1 | dsget user -sid
sid
S-1-5-21-3150332139-2813398079-754052488-1110
dsget succeeded

Hi Tony,

The SID is not resolved to a user (or group) because the object has been deleted in Active Directory (hence any lookup on that SID will fail). You need to restore the group or user in able to resolve it. See

Hi Matt,

I guess it is a built-in administrator of Netapp CIFS account.

How can I convert the bulit in administrator account to SID?

thanks.

Hi Tony,

You can view the SID for a local vserver user by using the same method...for example:

cluster1::> vserver cifs users-and-groups local-user show -vserver vserver1
Vserver User Name Full Name Description
------------ --------------------------- -------------------- -------------
vserver1 VSERVER1\Administrator Built-in administrator account

nclaunsw01::> set diag

Warning: These diagnostic commands are for use by NetApp personnel only.
Do you want to continue? {y|n}: y

cluster1::*> diag secd authentication translate -node local -vserver vserver1 -win-name Administrator
S-1-5-21-3601454379-3612699275-2053566262-500

I recommend reading the following article as this will help to understand the Syntax of a SID:

https://technet.microsoft.com/en-us/library/cc962011.aspx

Knowing this you can easily determin if the SID represents a local user or group verses a domain user or group by comparing the domain identifer in the SID. For example the domain identifer for the local administrator account in the above example is "21-3601454379-3612699275-2053566262" as compared to an AD user account with a domain identifier of "21-3150332139-2813398079-754052488". EG

cluster1::*> diag secd authentication translate -node local -vserver nvserver1 -win-name user1
S-1-5-21-3150332139-2813398079-754052488-1110

Hello,

I am having the same issue as mentioned above, however the groups are in AD and still SID translation is not happening.

I have checked almost everything, and still unable to find the issue.

diag secd command doesnt work for me on 8.3.2

Appreciate any help...

Thank you and Regards
