After the initial analysis to remove profiles that should not be migrated, you have a candidate data set of users and groups to import. The next step is to analyze the attributes in user profiles to identify any potential problems that you will need to address when you move the profiles into zones. Centrify Professional Services offers scripts that assist in this process. If you are analyzing the files manually or writing your own scripts, here are the common issues you need to check for:
- Determine whether any user name has more than one UID in the target set of computers. The UID is the primary way of determining file ownership and file permissions. On a single UNIX system, a user can only have one UID. However, across all of the computers in the target set, the same user name might have more than one UID.
- Determine whether any UIDs are associated with more than one user name.
- Determine whether any users have other profile conflicts, such as more than one primary GID, home directory, or shell on the computers in the target set.
In doing your preliminary analysis, keep in mind that you need to know which user profiles are associated with which people in your organization. For example, do the user names ldavis and davle refer to the same person (Len Davis) or to different people (Len Davis and Leslie Davidson).
This analysis of existing user profiles will help you identify the requirements of your initial zone design. The zone design allows you to use conflicting attributes as-is, without modifying any of the legacy data. You need to be aware of where there are conflicts so you can address them, but you do not need to change values for any attributes.
