ASA VPN with LDAP Authentication

Need help?
Log on to the Admin UI as openvpn administrative user. For example, if you use an SDI or certificate server for authentication, no authorization information is passed back. There's no need to click Update Running Server yet. Just odd how it works after I sign in with a local admin account for a little while and then stops after a period of time.

OpenVPN Access Server on Active Directory via LDAP

Hello Team, It needs to be simple mistake, i had it working, now it's not working. I authorize user in LDAP which hits authz rule having the following authorization profile: How does Cisco determine what's a Sender?

Created by Greg Muszynski on So I am looking at two Outgoing Senders reports: Created by elpollodiablo on Really simple question for a newb: I have a single web server that I want to share on a static IP. Create Please login to create content. As we continue with the sub commands, we provide a username and password for the ASA to use in order to log into AD and make sure the user exists. I usually let the Windows admin dictate the name. In order to have a successful implementation, you can use the following command to test the LDAP authentication: If the test fails, I recommend you stop and figure out the AD problems first.

Still in subcommands, we add our second layer of authentication by telling the ASA t o also check against the LDAP attribute created in step 1. The next step is to point the existing production VPN tunnel group to the new authentication servers created earlier. First we enter the VPN group policy section, and then assign the appropriate authentication method. Note, there are other attribute settings for this group, however, we only care about the authentication method.

The ASA automatically defers to the default group policy if a user authentication fails and no authentication method is specified, therefore, we need to make sure that the built-in default policy is using the same authentication method. The fiirst step is to change the default tunnel group defaultRAGroup to utilize the same authentication method. Finally, the VPN default group policy attributes are basically disabled by changing the simultaneous logins to zero. Now it is time to test.

The ASA has a simple debug command to verify the results. Here is a sample debug of the LDAP authentication. If the match is being performed properly, the rest depends on the users group membership. In addition, this debug command can be very useful to find out where the authentication maybe failing.

If it is valid, then some user properties in the LDAP directory are sent to the Access Server along with an "ok" message indicating that the credentials were fine. Then, based on settings in the User Permissions page on the Access Server, the user is allowed to connect, with standard permissions or with permissions you've set in the User Permissions table. Since we are only going to be contacting the LDAP server for authentication of users, all we really need is the ability to look up the user and verify the password for the account.

This requires only limited access. In our guide we are going to be creating a new standard user without administrative privileges, and give it a secure password, and deny it the ability and requirement to alter the password.

This is to ensure the account credentials will continue to function in the future. If you are familiar with security settings you may of course implement it in whatever you wish and limit this user account even further, just as long as you can still use it to bind to the LDAP server and perform user authentication.

Open the Active Directory Users and Computers panel. Set a secure password and make it so the password never changes. You can then make mistakes in this process without losing access to the Admin UI. Log on to the Admin UI as openvpn administrative user. Click save settings to store the changes. There's no need to click Update Running Server yet. This time make sure to click Update running servers to implement the changes.

At this point, authentication via LDAP should now be working. If you have problems authenticating we suggest checking the authentication problems troubleshooting page. Once you have authentication against LDAP working properly, we recommend you add a user to the User Permissions table for administrative purposes only, and assign it the admin privilege.

This user account must of course be a valid and existing user account in the LDAP directory server. This user account can then be used to perform administrative tasks. By default, removing a password in the Linux operating system automatically means you cannot use the account to log in. But you can still apply permissions to users authenticating at the Access Server.

Something to keep in mind however is that LDAP is by default case insensitive.

Under VPN Access tab select the appropriate address objects/groups that your LDAP User or LDAP Group will need access to and click the right arrow to Add Network to Access List.
