Explanation: This error code is returned when you perform a query against one or more attributes that are currently being maintained (reorganized for more optimal storage).
Action: This is a temporary condition. Generally, if you try the query again later, the maintenance will have been completed, and the error will no longer be returned. The amount of time it takes for the attribute maintenance to finish depends on the size of the directory. Maintenance takes longer for larger directories because essentially every object in the directory is checked.
