  • max amount of users

    Is there a maximum amout of users that can be entered into one AD? we plan on entering 5000 names. Are we going to have any issues?

    Also is there a way to import many users into AD instead of adding them one by one?


    Thank you to all who respond

    Nope... no problems with the 5000 users.

    Yes, there is an way to import a lof of users at once.
    PLease review CVSDE for example;

          Where you want to import from?

          The recommended limit is to perform no more than 5,000 operations per LDAP transaction. An LDAP transaction is a group of directory operations (such as add, delete, and modify) that are treated as one unit. If your script or application performs more than 5,000 operations in a single LDAP transaction, you are at risk of running into resource limits and an operational timeout. If that happens, all the operations (changes, additions, and modifications) in the transaction are rolled back, which means that you lose all those changes.

              As an example, we have 28,000 users in our AD. Oh, and 130,000 groups as well. Don't ask.

              But - we haven't run into any of the issues which you seem to be anticipating.

                Note that this limitation does not exist when LVR is turned on and you perform a single transaction that modifies a linked-value attribute with more than 5K changes.
