Indexing attribute forbids accessing associated records

[Guy Marcenac <guy@posteurs.com>]

Hello,

I am trying to use LDAP for unix authentication. I use slapd 2.1.30 on 
debian sarge. I populated the directory, set up pam and nss.
It works fine with ssh, su, sudo ...

But I cannot index the attributes I use to access data. There is 
probably something obvious I missed, but ...

When I index uid attribute with
index  uid     eq
the record isn't found anymore.

if I
ldapsearch -x -b 'dc=example,dc=com' '(uid=test)'
I get the result if this attribute isn't indexed, and the trace in the 
log looks like this:

*without 'index uid eq' in slapd.conf*
