[Bryan Burgin]

Günther,

I should have waited a few seconds longer as I just received feedback from the product group.  Below are your questions and answers.  Updates will be made to the technical documents in a future refresh.  Please let me know if this resolves your questions.

Thank you for your patience.

Bryan

Q1: Is CountOutgoingAuthInfos defining the number of CurrentOutgoingAuthInfos *and* PreviousOutgoingAuthInfos in total, n-times both structs or just n-times CurrentOutgoingAuthInfos ? In any case, is it up the user to figure out the number of PreviousOutgoingAuthInfos from calculation with the offsets ?

(likewise for CountIncomingAuthInfos and CurrentIncomingAuthInfos and PreviousIncomingAuthInfos)

A: PreviousOutgoingAuthInfos is either an array of 0 elements or an array of exactly the same number of elements as CurrentOutgoingAuthInfos (this number is CountOutgoingAuthInfos). Same applies to CountIncomingAuthInfos and  CurrentIncomingAuthInfos and PreviousIncomingAuthInfos 

Q2: "CountIncomingAuthInfos": is there a typo ? It says: "Specifies the count of entries present in the CountIncomingAuthInfos field"

A:  Yes, It should say "Specifies the count of entries present in the CurrentIncomingAuthInfos field"

Q3: Which values do ByteOffsetCurrentOutgoingAuthInfo and ByteOffsetPreviousOutgoingAuthInfo have in case CountOutgoingAuthInfos is 0 ?

(likewise for ByteOffsetCurrentIncomingAuthInfo and ByteOffsetPreviousIncomingAuthInfo and CountIncomingAuthInfos)

A: ByteOffsetCurrentOutgoingAuthInfo will always be 12 ([CountOutgoingAuthInfos][ByteOffsetCurrentOutgoingAuthInfo][ByteOffsetPreviousAuthInfos]) as it points to where the CurrentOutgoingAuthInfo array begins (which remains the same irrespective of how many entries are in the array). 
     In this case (when CountOutgoingAuthInfos is 0), ByteOffsetPreviousOutgoingAuthInfo will also be 12  as it points to where the PreviousOutgoingAuthInfo array begins (which is ByteOffsetCurrentOutgoingAuthInfo + size of CurrentIncomingAuthInfos and the latter is 0).

Günther,

Just a quick update.  I am expecting a reply from development very soon.  As soon as I have a solution for you I'll pass it on.

Guenther,

I am reviewing this for you and will be making a request to improve the document.  The case to track this issue is SR 110092949275537.

Hi Darryl,

here are some questions for clarification for the LSAPR_TRUSTED_DOMAIN_AUTH_BLOB struct as defined in MS-LSAD 2.2.7.16:

* Is CountOutgoingAuthInfos defining the number of CurrentOutgoingAuthInfos *and* PreviousOutgoingAuthInfos in total, n-times both structs or just n-times CurrentOutgoingAuthInfos ? In any case, is it up the user to figure out the number of PreviousOutgoingAuthInfos from calculation with the offsets ?

(likewise for CountIncomingAuthInfos and CurrentIncomingAuthInfos and PreviousIncomingAuthInfos)

* "CountIncomingAuthInfos": is there a typo ? It says: "Specifies the count of entries present in the CountIncomingAuthInfos field"

* Which values do ByteOffsetCurrentOutgoingAuthInfo and ByteOffsetPreviousOutgoingAuthInfo have in case CountOutgoingAuthInfos is 0 ?

(likewise for ByteOffsetCurrentIncomingAuthInfo and ByteOffsetPreviousIncomingAuthInfo and CountIncomingAuthInfos)

Thanks,

Guenther
