Preparing the user community in a production deployment
As you prepare to migrate a set of users to Active Directory, you should provide training or informational materials to inform that user community about what to expect. For example, if your organization has decided to implement policies that prevent locally-defined user accounts from accessing some computers, be sure that the user community affected by this policy understands the change. Similarly, if your organization has decided to eliminate service accounts or restrict access to computers previously available, you should communicate these changes and notify users about any migration issues that may affect file access permissions and file ownership.
When you are ready to migrate a specific set of users, you should inform the user population about the upcoming deployment by providing the following information:
- Schedule for deployment. Make sure that department managers and end-users know when the switch to Active Directory is scheduled to occur.
- Computers and applications affected. Make sure that department managers and end-users know if their workstations or the servers they access for business applications are included in the deployment. If users need access to a computer that is being added to an Active Directory domain, they need to know whether their user account is in the same domain as the computer or a different domain. If there are applications hosted on a computer that is being added to an Active Directory domain, users need to know how this will affect access to the hosted application. For example, users may need to select a domain when logging on, or log on using the user_name@domain_name format.
- Active Directory account information. Make sure that end-users know their Active Directory account information and understand that they must use their Active Directory password to access their UNIX workstations after the deployment is complete. You should inform users about the valid logon names and formats they can use, the Active Directory password assigned to their account if it is a new account, whether they are required to change their password when they next log on, and any password complexity rules you have implemented. Active Directory may lock accounts if users attempt to log on using their UNIX password, which could result in a large number of Help Desk requests for password resets.
- Changes to access policies. Make sure that department managers and end-users are aware of any changes to access control policies. For example, if you are using group policies to deny access to some users or groups who could previously log on to a computer, you should inform those users or groups of the change and that it will take effect after the migration to Active Directory.
