bdb_search: 112 does not match filter

Hi there guys.

A costumer of us were having problems with the slapd service ( unexpected hangs ), it's an ubuntu installation running slapd 2.2.26
 In the logs I noticed that there were no indexes  available, the index_param failed were reported in the logs, the systems uses ldap for user authentication and nothing else.

After that, I added the following in the slapd.conf, 

index          cn,gidNumber,memberUid,uid  eq
index          uniqueMember    eq
index          uidNumber       eq

The performance where better and there were no more hangs, but I'm getting the following error.
and the user cannot authenticate, so I went back to the original configuration without indexes.

Reading in the list I found that some  people suggest to add more index, but, what else can I add?
this is the structure.

dn: uid=user,ou=People,dc=domain,dc=gub
cn:: THVjw61hIENhbGRlcw==

objectClass: person
objectClass: posixAccount
objectClass: top
sn: Name
uid: user
uidNumber: 1542
userPassword:: bGNhbGRlcw==
structuralObjectClass: person



Thanks in advance.
Best Regards.
