Most tests here relies on the availability of an LDAP server configured with TLS.

Client/Server configuration:
===========================================================
OpenLDAP 2.3.43 has been used with the configuration below.

Notes:
1.  A self signed certificate can be generated using:
    $ openssl req -newkey rsa:1024 -x509 -nodes -out server.pem -keyout server.pem -days 3650
    It is used for testing ldap_start_tls(), which also requires "TLS_REQCERT never" in client configuration
2.  An empty LDAP structure is required for the tests to be PASSed

(/etc/openldap/)slapd.conf:
-----------------------------------------------------------
TLSCACertificateFile /etc/openldap/ssl/server.pem
TLSCertificateFile /etc/openldap/ssl/server.pem
TLSCertificateKeyFile /etc/openldap/ssl/server.pem
TLSVerifyClient never

# hdb is used instead of bdb as it enables the usage of referrals & aliases
database        hdb
suffix          "dc=my-domain,dc=com"
checkpoint      32      30
rootdn          "cn=Manager,dc=my-domain,dc=com"
rootpw          secret
directory       /var/lib/openldap-data
index   objectClass     eq

authz-regexp
	uid=Manager,cn=digest-md5,cn=auth
	cn=Manager,dc=my-domain,dc=com


(/etc/openldap/)ldap.conf:
