PIUserIncompatible user and PIGroupIncompatible group

Old-model administrative tools (Point Builder, SMT, and so on) expect access permissions in the owner/group/world model. Data Archive (versions 3.4.380 and later) uses a different access permissions model. When old administrative tools try to view or modify access permissions on a new Data Archive server, Data Archive attempts to determine an owner and group.

If Data Archive cannot determine an appropriate owner or group, then it defines the owner as the user PIUserIncompatible and the group as PIGroupIncompatible. On Data Archive version 3.4.380 and later, PIUserIncompatible and PIGroupIncompatible are provided for this purpose. They do not appear in the list of users and groups by default. To show them, click the Options button.

If the access permissions for the object meet the following format, then Data Archive can determine an owner and group for the object:

• One (and only one) PI user

• One (and only one) PI group

• PIWorld identity

If any of these conditions is not met, Data Archive cannot determine an owner and group and it uses the PIUserIncompatible user and PIGroupIncompatible group instead. Therefore, these names are displayed as the owner and group in older tools. You can change the names to something more descriptive, if you want.
