System.FormatException: Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

The above exception was thrown when searching for a DN in the adapter space.

3 issues:

1. While perfectly reasonable that such a search is nonsensical at a low enough level, the user experience is horrible.  No error should be thrown at all, just no results returned.  If, however, an error has to be returned it should be in the form of a user friendly message on the page (or in the old days this would have been in a dialog) - without the ugly stack trace.
2. It is not clear from the search page how one should search for the DN of an object that appeared in the logs.  The alignment of the data grid with the column header was skewed and I incorrectly guessed that the column header for IdBId might have been the DN header.
3. I was unable to clear the adapter entity search filter after this error.

Using: UNIFY Identity Broker Management Studio v5.0.5 Revision #0
