ldapsearch not accurate

[Cory Petkovsek <cory@adaptableit.com>]

I'm experiencing what I think to be a logic error, but I'm not sure if
it is slapd's logic or mine.  I'm using the qmail schema in addition to
the default set.  Debian slapd 2.1.22-1.

When I search by mailAlternateAddress I get a result if mail==uid, but
otherwise not.  Can someone explain this to me please?  Please obvserve
my simple successful and unsuccessful queries.

Thanks,
Cory
