OTRS + LDAP TLS

Net::LDAP new params (if needed - for more info see perldoc Net::LDAP)
        Params => {
            port => 389,
            timeout => 120,
            async => 0,
            version => 3,
        },

new ( HOST, OPTIONS )

Creates a new Net::LDAP object and opens a connection to the named host.

HOST may be a host name or an IP number. TCP port may be specified after the host name followed by a colon (such as localhost:10389). The default TCP port for LDAP is 389.

You can also specify a URI, such as 'ldaps://127.0.0.1:666' or 'ldapi://%2fvar%2flib%2fldap_sock'. Note that '%2f's in the LDAPI socket path will be translated into '/'. This is to support LDAP query options like base, search etc. although the query part of the URI will be ignored in this context. If port was not specified in the URI, the default is either 389 or 636 for 'LDAP' and 'LDAPS' schemes respectively.
