    Active Directory GUIDs [Resolved]

    We have just received a service which queries the Active Directory of the domain and populates a database table with two fields: LoginId and a corresponding GUID.

    My question is regarding the GUID. How are these generated, are they in the AD itself or would it be done by the service? If they are from the AD, are they constant for each user, or can they ever change?

    Re: Active Directory GUIDs

    GUID is supposed to be unique so I would carefully assume that they are constant relating to either the user sid or someting in that
    service. Without knowing what the service is doing it may be hard to determine where they're coming from or related to.

    What does the service do?

    Re: Active Directory GUIDs

    I asked a bit, and have come to the conclusion that the service gets the GUID from ActiveDirectory. So that part's OK.

    My second question still remains, though. Can the GUID retreived from Windows ActiveDirectory ever change? Under what circumstances?

    Re: Active Directory GUIDs

    Isnt the GUID the user SID#? If it is then it should not change at all.

    Re: Active Directory GUIDs

    I don't think that GUID is the same as a COM GUID. It is constant to each user, and will not change unless you delete the user and re-create it.
    Nobody knows what software they want until after you've delivered what they originally asked for.

    Don't solve problems which don't exist.
