search relult empty after adding indexes

[Prune <Prune@lecentre.net>]

Hi,

I just add some indexes to my slapd.conf :

# Indices to maintain
index           objectClass     pres,eq
index           uid,mail pres,eq,sub
index           cn,sn pres,eq,sub,subany

and run slapindex and restart the ldap server.

Now when I do a search, it returns nothing :

begin get_filter
EQUALITY
end get_filter 0
conn=0 op=2 SRCH base="dc=lecentre,dc=net" scope=2 
filter="(mail=toto@copain2000.com)"
       AND
       DN SUBTREE
       OR
       EQUALITY
       EQUALITY
       EQUALITY
ber_flush: 14 bytes to sd 9
conn=0 op=2 SEARCH RESULT tag=101 err=0 text=


When I erase the 'mail' attribute from the second index, everything goes 
well.
why ?

Cheers,

Prune
