problem with back-sql and getting error about no structural object class provided

["Neulinger, Nathan" <nneul@umr.edu>]

I added:

                        Debug( LDAP_DEBUG_TRACE, "backsql_id2entry(): "
                                "failed structural class check (%s)\n",
text, 0, 0);

in the failure case in back-sql/entry-id.c after it checks
structural_class(). I get a complaint about no structural object class
provided.

Any ideas on what could be causing this problem? Database structure I'm
testing with is very simplistic. Object class of what I'm returning is
'umrAccount', which is a posixAccount with a single added attribute. 

Here's what I see in a trace:
