Re: Reading msexchMasterAccountSid

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hello,

this has nothing to do with Exchange at this point. It's Active Directory.

If the SID you are trying to resolve is from a different domain or so, the translation-process may fail. Is the failing SID a short one?
If you want to translate the SID on a specific computer, you can use the ResolvedIdentityReference from my InfiniTec.Security package on my website (www.infinitec.de). In the constructor, you can specify a remote computer which will do the translation.

Best regards,
Henning

Many thanks Henning for your response.

I have advanced considerably, thanks to your help, but get a
System.Security.Principal.IdentityNotMappedException error when I
attempt objSecurityIdentifier.Translate(GetType(NTAccount)).

I'm learning about Exchange security. Can you tell me what causes this
error?

TIA

Hello,

that field contains a SecurityIdentifier (SID). In Text-form this is
something like S-1-5-xxxxxxxxx....

If you are working with .NET 2.0 you can wrap that text in a
SecurityIdentifier and call sid.Translate(typeof(NTAccount)) which translate
the SIDs to NT4 account names.

Best regards,
