LDAP : ldapsearch segfault error

Question

I am confronted with a problem using openLDAP and ldapsearch. The server is RHEL6.1 and the configuration of ldap is normally correct, many other servers with the same LDAP configuration work well. When I run ldapsearch -x -ZZ command, I got the following error : Segmentation fault (core dumped)

Here is the last lines from ldapsearch -x -ZZ -d -1 :

ldap_msgfree
TLS: certdb config: configDir='/etc/openldap/cacerts' tokenDescription='ldap(0)' certPrefix='' keyPrefix='' flags=readOnly
TLS: cannot open certdb '/etc/openldap/cacerts', error -8192:Unknown code ___f 0

TLS: error: the certificate '/etc/openldap/cacerts/servad01/servad01.crt' could not be found in the database - error -8187:Unknown code ___f 5.
Segmentation fault (core dumped)

The file servad01.crt exists :

[root openldap]# cat 
/etc/openldap/cacerts/servad01/servad01.crt
-----BEGIN CERTIFICATE-----

[...]

-----END CERTIFICATE-----

It's a little late but the problem was solved by installing nslcd
