If I run Openldap with -d 1 option and i execute

ldapsearch -h ldap01.uc3m.es -b "o=Universidad Carlos III,c=es" 
"(&(uid=nacho)(objectclass=inetorgperson))" -a always -x

then i could see in my terminal a lot of lines like this

entry_decode: "uid=xxxxxx, ou=Externos,o=Universidad Carlos III,c=es"
<= entry_decode(uid=xxxx,ou=Externos,o=Universidad Carlos III,c=es)
entry_decode: "uid=xxxx,ou=Receptores,ou=sfe2010,ou=Grupos,o=Universidad 
Carlos III,c=es"
<= 
entry_decode(uid=xxxx,ou=Receptores,ou=sfe2010,ou=Grupos,o=Universidad 
Carlos III,c=es)
=> bdb_dn2id("uid=exxx,ou=receptores,ou=sfe2010,ou=grupos,o=universidad

...... thousands & thousands of similar lines (each search with always 
dereferencing look up almost whole directory entries)

and i can't obtain any result because the operation takes a lot of time 
(more than 50 seconds.)

In my var/openldap-data directory there is a index for aliasedObjectName
    835584 2010-01-11 13:01 aliasedObjectName.bdb
thanks to that, i achieve better response times.


Thanks
