Hi all,

We have an OpenLDAP server (RHEL6) running version 2.4.23-15, and we have clients in RHEL5 and RHEL6.
With clients in RHEL5 works properly but I found some problems with RHEL6 clients in versions newer than 2.4.19-15.

In the clients, if I try to upgrade to new versions than 2.4.19-15 then the client stops working:

[root@XX ~]# rpm -qa | grep openldap
openldap-2.4.19-15.el6.x86_64
openldap-clients-2.4.19-15.el6.x86_64
[root@XX ~]# ldapsearch -x -D 'cn=authenticate, ou=System,dc=test, dc=es' '(objectclass=*)' -W -ZZ
Enter LDAP Password: 
# extended LDIF
#
# LDAPv3

I have the same configuration files that used with the older version. I use these configuration files:

/etc/pam_ldap.conf:
base dc=test,dc=es
binddn cn=authenticate,ou=System,dc=test,dc=es
bindpw XXXX
timelimit 120
bind_timelimit 120

/etc/openldap/ldap.conf:
URI ldap://ldap1-test/ ldap://ldap2-test/
BASE dc=test,dc=es
TLS_CACERT /etc/openldap/cacerts/catest.crt

CAcert file:

[root@XX ~]# ls -l /etc/openldap/cacerts/catest.crt
-rw-r--r--. 1 root root 1655 May 23 15:23 /etc/openldap/cacerts/catest.crt

Any idea on what the issue is? Am I missing anything?

Thanks in advance,
