In most cases, you can ignore all UNIX users with a UID less than 99 because those are the default operating system accounts. You may also want to skip migration for some or all UNIX service accounts unless you explicitly want to manage those service accounts, and any privileged commands they run, through Active Directory and zones.
You can manage the passwords for UNIX service accounts using Access Manager without having those accounts defined in zones or in Active Directory. Therefore, you may want to leave most or all of the service accounts as locally defined accounts.
In general, the only reasons to migrate default system or service accounts to Active Directory are:
- If you want to use Active Directory password policies for the account.
- If the service account itself owns one or more privileged commands that you want to manage through Centrify role definitions rather than locally in the sudoers file.
Typically, only service accounts that own special permissions, such the oracle user account, are migrated to Active Directory.
