OpenVPN issue TLS

Hi,

i have problems setting up an OpenVPN connection and i do need help about it.
The error message i get is:
Options error: specify only one of --tls-server, --tls-client, or --secret

My setup:
Port 1194
dev_type tun
nobind
float
persist_tun
persist_key
comp_lzo adaptive
proto udp
auth SHA1
cipher BF-CBC
keysize 128
tls_cipher TLS-RSA-WITH-AES-128-CBC-SHA
ns_cert_type server
remote de.vpnunlimitedapp.com
ca
cert
key

It seems that I have a double config somehow, but not sure where or how.

Has somebody a good idea?

Thanks
