Hello,
I have some problems, probably very easy ones but I am total new to this
kind of implementation.
I have to configure an OpenVPN Server on a Raspberry Pi that
authenticates against LDAP. I have a little experience with an OpenVPN
Server that don't use LDAP. I installed openvpn-auth-ldap and edited
auth-ldap.conf.
<LDAP>
# LDAP server URL
URL ldap://ldap.jumpcloud.com:636
# Bind DN (If your LDAP server doesn't support anonymous binds)
# BindDN uid=Manager,ou=People,dc=example,dc=com
# Bind Password
# Password SecretPassword
# Network timeout (in seconds)
Timeout 15
# Enable Start TLS
TLSEnable yes
# Follow LDAP Referrals (anonymously)
FollowReferrals yes
# TLS CA Certificate File
TLSCACertFile /usr/local/etc/ssl/ca.pem
# TLS CA Certificate Directory
TLSCACertDir /etc/ssl/certs
# Client Certificate and key
# If TLS client authentication is required
TLSCertFile /usr/local/etc/ssl/client-cert.pem
TLSKeyFile /usr/local/etc/ssl/client-key.pem
# Cipher Suite
# The defaults are usually fine here
# TLSCipherSuite ALL:!ADH:@STRENGTH
</LDAP>
<Authorization>
# Base DN
BaseDN "o=BaseDN_I_got_from_the_LDAP_admin,dc=jumpcloud,dc=com"
# User Search Filter
#SearchFilter "(&(uid=%u)(accountStatus=active))"
SearchFilter "(&(uid=%u))"
# Require Group Membership
RequireGroup false
# Add non-group members to a PF table (disabled)
#PFTable ips_vpn_users
<Group>
BaseDN "ou=Groups,dc=example,dc=com"
SearchFilter "(|(cn=developers)(cn=artists))"
MemberAttribute uniqueMember
# Add group members to a PF table (disabled)
#PFTable ips_vpn_eng
</Group>
</Authorization>
My OpenVPN server.conf is:
port 1194
proto udp
dev tun
sndbuf 0
rcvbuf 0
ca ca.crt
cert server.crt
key server.key
dh dh.pem
auth SHA512
tls-auth ta.key 0
topology subnet
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 192.168.0.1"
keepalive 10 120
cipher AES-256-CBC
comp-lzo
user nobody
group nogroup
persist-key
persist-tun
status openvpn-status.log
verb 3
crl-verify crl.pem
plugin /usr/lib/openvpn/openvpn-auth-ldap.so
/etc/openvpn/auth/auth-ldap.conf login
client-cert-not-required
I copied my client.ovpn and the ca.crt from the OpenVPN Server to my
Windows 10 machine and installed OpenVPN-Gui. Now a connection to the
vpn server is working and I could login in the network. Now I have the
following questions:
I could login but I didn't have to pass my LDAP user und password for
login. The jumpcloud admin made a test account for me. How to validate
this?
And is it normal that you could login without any user and password? All
I did was copying the client.ovpn and ca.crt to the config folder of
OpenVPN-Gui.
Thanks for help and greetings
