Search returning nothing with 2.1.25, but ok with 2.0.27

Hi

	I'm experiencing a problem while searching my user database
after 2.0.27 -> 2.1.25 migration. I've searched in the archives
and found nothing, sorry if it was a discussed thread.
	I've compiled 2.1.25 with ldbm (gdbm) backend, dumped
my user database from 2.0.27 with slapcat and populated
it within 2.1.25 with slapadd. Everything looks fine:

<snip>
added: "uid=paulobarbosa,ou=People,dc=emprel,dc=recife" (00000cc0)
added: "uid=veridiana,ou=People,dc=emprel,dc=recife" (00000cc1)
added: "uid=manoelmoraes,ou=People,dc=emprel,dc=recife" (00000cc2)
added: "uid=elisabetegomes,ou=People,dc=emprel,dc=recife" (00000cc3)
</snip>

	configured in slapd.conf:

allow	bind_v2

database        ldbm
suffix          "dc=recife"
rootdn          "cn=admin,dc=recife"

index   objectClass,uid,uidNumber,gidNumber,memberUid   eq
index   cn,mail,surname,givenname                       eq,subinitial


	When searching my old server (2.0.27):

# ldapsearch -x -h oldserver -b 'dc=emprel,dc=recife' uid=brasilino
version: 2

#
# filter: uid=brasilino
# requesting: ALL
#

# brasilino, People, emprel, recife
dn: uid=brasilino,ou=People,dc=emprel,dc=recife
cn: Lucas Brasilino
givenName: Lucas
<snip>

	But on my new one (2.1.25):

# ldapsearch -x -h newserver -b 'dc=emprel,dc=recife' uid=brasilino
version: 2

#
# filter: uid=brasilino
# requesting: ALL
#

# search result
search: 2
result: 0 Success

# numResponses: 1

	It only work when:

# ldapsearch -x -h newserver -b 'dc=emprel,dc=recife' uid=brasilino*

	it works! I.e. when using a mask "*".
	The problem is that many applications, like Mozilla and Linux
PAM, seems not using "*".
	Running slapd daemon in debug mode, I've got the following when
doing the first search (uid=brasilino):

<snip>
=> ldbm_cache_open( "/var/lib/ldap/uid.gdbm", 34, 600 )
<= ldbm_cache_open (cache 7)
=> key_read
<= index_read 0 candidates
<= equality_candidates NULL
<= equality_candidates 0
<= filter_candidates 0
<= list_candidates 0
<= filter_candidates 0
<= list_candidates NULL
<= filter_candidates 0
====> cache_return_entry_r( 222 ): returned (0)
ldbm_search: no candidates
send_search_result: err=0 matched="" text=""
</snip>

	No candidates??!?!
	
	Anybody can point me where I'm messing things up? :)

Happy New Year.
regards
