<ol>
<li>Log into OpenVPN Access Server</li>
<li>Click Authentication &gt; LDAP in the left navigation menu</li>
<li>Click the Use these credentials toggle to Yes</li>
<li>Fill in the LDAP configuration form as follows:
<p>LDAP host: i12bretro.local<br />
Base DN: CN=Users,DC=i12bretro,DC=local<br />
Username Attribute: sAMAccountName<br />
Bind DN: readonly_svc@i12bretro.local<br />
Additional LDAP Requirements: memberOf=CN=VPN Users, CN=Users, DC=i12bretro, DC=local</p>
</li>
<li>Click the Save Settings button</li>
<li>Click User Management &gt; User Permissions in the left navigation</li>
<li>Create a new username matching an LDAP user name and click the Admin checkbox</li>
<li>Click the Save Settings button</li>
<li>Go back to Authentication &gt; LDAP in the left navigation menu</li>
<li>Click the Use LDAP button</li>
<li>Click the Update Running Server button</li>
<li>Click Logout at the bottom of the left navigation</li>
<li>Log back in with the newly created user and their Active Directory password</li>
</ol>
<p>Note: If LDAP authentication fails, revert back to local authentication using the following commands:<br />
cd /usr/local/openvpn_as/scripts<br />
./sacli --key &quot;auth.module.type&quot; --value=&quot;local&quot; ConfigPut<br />
./scali start</p>
<p>If you ever mess up the OpenVPN AS configuration beyond repair, run the following command to reset the configuration back to defaults and try again:<br />
ovpn-init --force</p>
