I need to search for a few different attributes very quickly for the application

I am working on, these include objectClass, mail, modifiersName and some others

beside.  There for I created entries in the slapd.conf file to index these
attributes
with entries like this:

index           modifiersName eq,pres
index		objectClass eq,pres
index		mail eq,pres

The complete slapd.conf file is included at the end of this message.

After altering the slapd.conf file, I stopped slapd, ran slapindex and
re-started 
slapd.  slapindex created dbb files for each of the indexes I configured in the
configuration file but although searching for mail, objectclass worked
correctly,
searching with '(modifiersName=cn=amdin,dc=alecto,dc=zeus,dc=com)' or similar 
returned no results at all.  Peculiarly, searching for modifiersName equal to
the 
prevelidged user(cn=manager,dc=alecto,dc=zeus,dc=com) did still work.

One other very interesting point: if only modifiersName is indexed searching for

modifiersName works correctly. ie.

index		modifiersName eq,pres
#index		objectClass eq,pres
#index		mail eq,pres

Of corse I had to stop slapd, re-index using slapindex and restart slapd first.

For a simple test I used the following LDIF entries to populate the directory.

dn: dc=alecto, dc=zeus, dc=com
objectclass: dcObject
dc: alecto

dn: cn=admin, dc=alecto, dc=zeus, dc=com
objectclass: person
cn: admin
sn: admin
userPassword: {SSHA}5haTgkHLy+H4y7e4AWstZJf9MEtK/kJZ

dn: cn=interface, dc=alecto, dc=zeus, dc=com
objectclass: person
cn: interface
sn: interface
userPassword: {SSHA}KaIdiFG/+mHIjUhoZin9iPfwz1+YLmZ6

dn: ou=Clients, dc=alecto, dc=zeus, dc=com
objectclass: top
objectclass: organizationalUnit
ou: Clients

I used slapadd to populate the directory but it makes no difference if I use
ldapadd.
