There is a problem locating entries where a value in a multivalued attribute is
deleted.  The search filter should use the multivalued attribute using '*' on
the leftmost side, i.e. mailalternateaddress=*somedomain.com.
Kurt D. Zeilenga <Kurt@OpenLDAP.org> says that this is an indexing bug in
1.2.9.
I guess this would only be noticed if you have multivalued attribute.

Here are outputs from openLDAP command line tools to reproduce the problem:

* Start by displaying current data

[bench@ldap tools]$ ./ldapsearch -b "dc=surfshop.net, dc=ph"
"mailalternateaddress=*somedomain.com.ph" 
-D "cn=test, dc=surfshop.net, dc=ph" -W
Enter LDAP Password:

cn=bench, dc=surfshop.net, dc=ph
cn=Benjamin de los Angeles Jr.
sn=de los Angeles
objectclass=person
objectclass=organizationalPerson
.
.
.
mailalternateaddress=zwark@somedomain.com.ph
mailalternateaddress=lazone@somedomain.com.ph

* Delete a value from a multivalued attribute using modify

MODIFY Data in a file:

dn: cn=bench, dc=surfshop.net, dc=ph
changetype: modify
delete: mailalternateaddress
mailalternateaddress: lazone@somedomain.com.ph

[bench@ldap tools]$ ./ldapmodify -v -D "cn=test, dc=surfshop.net, dc=ph"
                      -W -f tempdata/modify-delete
Enter LDAP Password:
delete mailalternateaddress:
       lazone@somedomain.com.ph
modifying entry cn=bench, dc=surfshop.net, dc=ph 
modify complete

* Display the matching entry again

[bench@ldap tools]$ ./ldapsearch -b "dc=surfshop.net, dc=ph"
                    "mailalternateaddress=*somedomain.com.ph" 
                    -D "cn=test, dc=surfshop.net, dc=ph" -W  

Enter LDAP Password:

(No output! This is the PROBLEM)

* Add again an entry

DATA in a file:

dn: cn=bench, dc=surfshop.net, dc=ph
changetype: modify
add: mailalternateaddress
mailalternateaddress: lazone@somedomain.com.ph
 
[bench@ldap tools]$ ./ldapmodify -v -D "cn=test, dc=surfshop.net, dc=ph"
                    -W -f tempdata/modify-add
Enter LDAP Password:
add mailalternateaddress:
        lazone@somedomain.com.ph
modifying entry cn=bench, dc=surfshop.net, dc=ph
modify complete

* Display the matching entry again

[bench@ldap tools]$ ./ldapsearch -b "dc=surfshop.net, dc=ph"
                    "mailalternateaddress=*somedomain.com.ph" 
                    -D "cn=test, dc=surfshop.net, dc=ph" -W
Enter LDAP Password:

cn=bench, dc=surfshop.net, dc=ph
cn=Benjamin de los Angeles Jr.
sn=de los Angeles
objectclass=person
objectclass=organizationalPerson
.
.
.
mailalternateaddress=zwark@somedomain.com.ph
mailalternateaddress=lazone@somedomain.com.ph

( Magic! There goes the entry again! =) )
