user admin privileges may be broken

In my initial testing of importing data to the target server I get the following error message.

domain 'domain-name-hidden': cannot resolve Account Id: user admin privileges may be broken

This is on Zimbra 7.2.3 Network Edition running on CentOS.

This IS a multi mailstore environment, with the Zextras core only installed and running on one of the 11 store servers. Before scheduling a brief maintenance to install the core on all hosts, could you tell me if the error above is likely due to me not having installed the core across all hosts? I'd like to have a little extra confidence that the install and mailboxd restarts will resolve this issue.

Thank you,
Matt
