+++ This bug was initially created as a clone of Bug #818723 +++

Description of problem:

Install latest RHEL 6.3 distro with openldap-clients-2.4.23-25.el6.

Install ipa-server, uninstall ipa-server and re-install ipa-server.

Server install will fail on installing and configuring the ipa client.

openldap-clients now uses NSS cert db

# ls /etc/openldap/certs/
cert8.db  key3.db  password  secmod.db


If you move these files, and try again .. client install is successful.

We set TLS_CACERTDIR to /etc/openldap/certs in ldap.conf with default openldap installation. This change was introduced as a fix for bug #742023. This might be the cause.

Together with Jan Vcelak I investigated this issue in ipa-client-install. The issue only occurs when the new openldap nss db is set in TLS_CACERTDIR configuration option. When its commented out in /etc/openldap/ldap.conf or

ldap.set_option(ldap.OPT_X_TLS_CACERTDIR, "")

is added to the LDAP connection initialization in ipa-client-install, the installation works OK. The second change can be used as a workaround until the issue in openldap is fixed.
