Some mapping between account names and security IDs was not done.

Explanation:

During the mapping of Unicode strings to Security IDs (or vice versa), some names could not be mapped. This is an informational message and typically means that either an account has been deleted or a domain controller could not be located to map some of the names.

User Action:

Either ignore the message, or wait and retry when the domain controller will be available.
