Entry not listed when requesting all entries with ldapsearch

I've added a new entry with ldapadd like this:

I've got this in a file (myfile.ldif):

dn: mail=someone@example.com,ou=alias,ou=postfix,dc=example,dc=com cn: Mr Someone mail: someone@example.com maildrop: someone@corporative.example.com sn: Boss objectClass: CourierMailAlias objectClass: person objectClass: top objectClass: inetOrgPerson

$>ldapadd -D "cn=admin,dc=example,dc=com" -w secret -x -h "localhost" -f myfile.ldif

I can see it if I search specifically for it with ldapsearch (no problem with this):

$> ldapsearch -x -b "mail=someone@example.com,ou=alias,ou=postfix,dc=example,dc=com" # extended LDIF # # LDAPv3 # base <mail=someone@example.com,ou=alias,ou=postfix,dc=example,dc=com> with scope subtree # filter: (objectclass=*) # requesting: ALL #

# someone@example.com, alias, postfix, someone.com dn: mail=someone@example.com,ou=alias,ou=postfix,dc=someone,dc=com cn: Mr Someone mail: someone@example.com sn: Boss objectClass: CourierMailAlias objectClass: person objectClass: top objectClass: inetOrgPerson maildrop: someone@corporative.example.com

# search result search: 2 result: 0 Success

# numResponses: 2 # numEntries: 1

Howerver, when I try to search for this entry with ldapsearch I can't see it if I list all the entries:

$> ldapsearch -x -b "ou=alias,ou=postfix,dc=example,dc=com" | grep "someone" $>

I have some other entries that were previously there and they are all listed. It's very extrange that in the complete list the new etnry doesn't get listed. Any idea?

Regards.
