Cisco Firewall :: ASA Version 8.2 (2) / Authenticate With Microsoft LDAP?
Jul 25, 2012
I am running ASA ver. 8.2(2) and all users are configured in the ASA. This ASA is uses as a VPN ASA and we are using it for remote access for external users. When a user is logged in, he gets all parameters that are need to continue working from outside, such as, IP, assigned to special group with special permissions and so on. All the parameters that are needed are configured under user attribute. See example below:
username username1 password xxxxxx == nt-encrypted
username username1 attributes
vpn-group-policy Basic
vpn-access-hours none
vpn-simultaneous-logins 1
vpn-idle-timeout 30
[code]....
Is it possible to live the user attributes as is and to force the users to authenticate via LDAP servers only?

I am trying to implement Microsoft LDAP server with our ASA 5520. The client is using Cisco VPN client and when I am trying to connect I am receiving the following error message:
"Secure VPN connection terminated locally by the client. Reason 413:User authentication failed"
I triggered the debug on the ASA 5520 and everything looks fine .The LDAP server is sending the right information without any error message.
Googled this error message and I found that I need to enable the simultaneous logins to enable. I enabled it but I got the same error message. This configuration is under remote access vpn>group-policies>General>more options.

I'd like to configure wireless access from winXP to authenticate with our corporate Novell LDAP through ACS
Setup:
WinXP SP3 --> WLC 4402 --> ACS 5.2 --> Novell LDAP
1. Our Novell LDAP server uses secure LDAP (port 636) to authentication user.On ACS 5.2, when we configure this option we need to select Root CA. Should the Root CA in ACS must be the same as the LDAP server's? (the LDAP's certificate issuer)
2. What kind of authentication that this setup supports? Does it support PEAP/MSCHAPv2 as in Windows Zero Configuration or it only supports PEAP-GTC, EAP-FAST, EAP-TLS (which means I have to use Intel Proset/Wireless software to configure).

I have a WLC 4404 with LWAPs, the customer has a microsoft LDAP and all users are joined to the domain and he wants the users to be authenticated against their domain accounts and this should be done automatically so that when users login to windows they are also authenticated and joined the WLAN.so how we can do that with the simplest way, without Radius server using only the LDAP and wwithout envolving any certificates.also i need to know when i add LDAP server to the WLC, how can i know that this LDAP is properly inegrated with the WLC?

I am transitioning from a Microsoft ISA server to a Cisco ASA 5510. So far so good, until it comes to getting AAA functioning properly. I have a Microsoft IAS server that is functioning properly, however when I try to test it through the ASA's ASDM it errors out. When I run a packet trace it shows it's being blocked by the dreaded implicit ACL. The funny thing is that I can ping and traceroute to the IAS server from the ASA. I found numerous config examples for AAA using IAS, but still not working.
Could it possibly be behaving this way because my ASA and my IAS server are on two different internal netowrks? (172.31.1.x-ASA, 10.1.1.x-IAS)

We just set up the AnyConnect SSL vpn on our ASA. I am able to establish a connection fine using the Cisco AnyConnect client. I would like to use the native Windows VPN client though if possible. What configuration changes on either the firewall or the client I would need to make for this to happen?

I have some users from another company who are visiting my company. The use outlook to access their mail. I think it is via RPC over https (ssl). When there are on my network they are unable to send messages but when the connect to an ISP directly they are able to send. I have a cisco 2821 as my internet router and an ASA5505 (8.0.5...i downgraded it from 8.2.3) as my firewall. I have not blocked anything from going out. Of note is that when other users use window live configured for gmail....which uses tls they are unable to send emails with atachements. Regular emails go though no problem. Hotmail can send atachments without a problem (there is no encrytion there). I have narrowed the issue down to how the firewall treats esmtp or tls traffic passing though it. I have already diabled inspect esmtp on the firewall.

I have a computer behind the ASA 5505 firewall. The computer needs to access Microsoft Activation Server. Reading some website information, I need to allow a huge list of servers that basically points to www and https traffic. Therefore, looking at this heavy requirements, I prefer to allow this computer to navigate to any https or http (www) server outside of the firewall.I have included my current asa 5505 configuration.

I have a 5515 ASA that has the webVPN configured on it and it is using active directory to authenticate. The client would like to set up groups in active directory and restrict access to those groups when they are connected to the webVPN. For example, they have a group in active directory that they only want to access their "web" interface. What is the best way to configure this on the asa?

I've gotten to the point where I can test against active directory and get in, also I can get AD groups from my server on the ASA. My problem, I can't connect in via my AnyConnect client on my Android. I immediately get a "log in failed" and I know I'm using the right username/pass. Doing a little troubleshooting, I have attached my AnyConnect debug log and the results of the "debug ldap 255" command on the ASA. Also, I've used ldp.exe to determine I can connect in with the username/password combo I'm using.Combing through the AnyConnect logs I see a few instances of "global error unexpected" but no Google searches have brought up anything useful.

my client wants to make videoconference call thorugh Microsoft Office Communicator, this should be operating between host from one site to another one, but we already configured some rules in the firewalls, and making some test I see that the videoconference use dynamic ports (1024 to 65535) and if we let to operate the videoconference we should remove all the rules in the firewall and that's not the point.

We have a Cisco secure VPN site to site tunnel between the 2 locations.Which ports are need to open on tunnel so that users can successfully use OCS over the site to site VPN tunnel.All the users are havning the main brach AD account.Using Wireshark captured the packets, found only port TCP 5060, after allowing this port over tunnel I can see the authentication window.The user authentication fails. Already port 3389, 80, 443 are allowed.The main requirement is to only have the Chat, Group Chat and file transfer. Not require AV traffic.OCS is using TCP. no TLS is configured.

I have allways configured and run LDAP Server Groups authenticating to Active Directory Domain Controllers using LDAP, never an issue, until I hit a Domain Controller running on a Windows Server 2008. I have been unable to authenticate with the common setting with an ASA5510 running 8.0.1.

ASA 5510 ASA 8.0 ASDM 6.1 I want some remote users to have split-tunnel connection, others not. I used Cisco Document ID 100936 "Allow Split Tunneling for AnyConnect VPN Client on the ASA Configuration...". I created a new Group Policy with split-tunnel enabled. I created a new Connection Profile and assigned to it the new Group Policy. When I authenticate at the AnyConnect client I get a dropdown of the 2 connecton profiles, to choose the one I want. Each of them works, enabling or disabling split-tunnel. But I want to assign a connection profile to the particular user, not give the user a choice. The problem is I'm using LDAP authentication. The Local Users I set up before LDAP are obsolete, assigning them a Group Policy does nothing. I really don't want to give up LDAP and force people back to another local password. But the LDAP authentication to Active Directory just says yes or no, it won't assign a connection profile. At the AnyConnect Connection Profiles page I have set a switch "Allow user to select connection profile, identified by its alias, on the login page. Otherwise, DefaultWebVPNGroup will be the connection profile". If I clear that switch every user will be assigned the same default profile, which does not work.

I am currently migrating a netscreen firewall to a asa 5515 version 8.6 The issue is setting up the management connectivity.
basically the management IP of the cisco asa is not advertised. But, we want to route a management IP through the management interface to interface Gi0/2.
so IP of management interface is say - 216.10.100.10. and the IP of the inside interface is say - 198.1.1.10/24 on our router we have a static route sending 198.1.1.0/24 to next hop of 216.10.100.10 (management interface of cisco asa).
On the Cisco ASA can I send the traffic to the inside interface and manage the firewall via ssh that way?

I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?

I try to convert a CISCO ASA 8.2 version to 8.4 BUT, I have a small or "little" problem :On Cisco ASA 8.2.x, i have a possibility to create multi-line global with different subnet.Example :
global (outside) 2 217.1.x.65-217.x.x.66 netmask 255.255.255.240
global (outside) 1 interface <-- Ip interface is other subnet : 217.3.x.3
global (outside) 2 217.1.x.67 netmask 255.255.255.240
nat (inside) 1 0.0.0.0 0.0.0.0
nat (dmz2) 2 192.168.4.0 255.255.255.0
What is the method or solution to translate multi-global in 8.4 ? with static translation in 8.4 : i try to use different server in inside's zone, but not in same network on outside. In 8.2 Firmware, it's very easy to use that, but in 8.3-8.4 version, i don't have some idea to manipulate ...
interface Vlan1

We have 2 firewalls on PIX facing the Internet and connected to interface e1 (behind it) an ASA version 8.3 Both the PIX (Firewall facing) and the ASA are on the same subnet.
By using Routing statements and statics I have been able to reroute specific traffic to the ASA5520 version 8.3 Now I need to inverse the 2 devices. The ASA5520 will be facing the Internet and the PIX will be behind it.Unfortunately the ASA5520 is refusing to route the traffic to the PIX. The access-lists are open accordingly and a NAT on the ASA has been created.
