Error validating user

We have a secondary Domino directory, listing users belonging to a different internet mail domain. This database is linked in the Directory Assistance database.Everything works fine except that when a server is restarted we get the following log message (only and for all the users belonging to the secondary address book ):

29/05/2008 10.07.12 Error validating user yyy/xxx/it while processing calendar appointment (NoteID: NT00032706) in database sincrolog\ssincrol.nsf: Cannot find user in Domino Directory

The problem, as documented in many posts, seems to be the $busyName Field of the calendar entry.

In this field however we have the correct user name (which of course does NOT appear in the main but only in the secondary directory…)

Does anybody know of a workaround or a fix in a release after 7.03 ?

That’s because the AdminP request that is throwing the error only services users who appear in names.nsf, the primary domino directory for the domain.

so no way to eliminate the message ?
