• VPN authentication and wireless through ACS 5.4

  Hello,
  
  I am  in the process of migrating from ACS 4.1.1.23 to ACS 5.4. I have migrated our users and Network Device Groups and configured external Identity stores like AD and RSA. I want to authenticate our Wireless users with AD and VPN users through RSA. I am unable to create policies to get this UP and working. I need help in this regarding the policy creation.
  
  As I am new to the ACS 5.4 any help with the step by step configuration of the WLAN and VPN
  
  authentication will be appreciated.
  Thanks in advance.
  Regards,

  This is possible by creating access to two Services: one that authenticates with AD and the other against RSA.

  Then have need develop a selection of Service policy that will result in one of these two services. One possibility could be NAS-Port-Type in the RADIUS dictionary which should be 'Wireless - IEEE 802.11.

• SSL VPN authentication using the ad group

  Hi all

  I tried to restrict users to authenticate to the SSL VPN using an ad server. I have install the AAA server with the IP address of the AD server and attributed to the connection profile as well; However, I see that any user who is a member of a group in AD is able to authenticate.

  I want to only users who belong to the group "VPN users" get authenticated while everyone and all those who have credentials of the AD and not even a part of the 'VPN users' group is making authenticated.

  Can someone advice how I can make the ASA authenticate users based on ad groups? I use the ASDM to configure my VPN RA.

  Thanks in advance!

  Kind regards

  Hey riri,.

  Try to use DAP to restrict access to users who belong to a specific ad group:

  Use the AAA attribute "LDAP .member of" to allow access to the users belonging to a specific group and deny access to other users.

• IPSec VPN authentication problem against AD by RADIUS/ISA

  As background, I have a VPN IPSec authentication against the local database upward and running with access to my internal network and work with zero issues.

  So I would move offshore to the local database authentication and boince it is outside my ad.  I am running 2003 server so I configure ISA Server RADIUS and think I have it properly configured.  It is registered in the AD, I added my asa as a customer radius, customized remote access and connection request policies.

  The test of authentication in the ASDM he succeeds with all users who need.

  During the test through my client vpn on a remote computer, I get the connection terminated by a peer, no reason given.

  It is said of the event on the domain controller logs

  -l' user domain - user % name % has had access.

  directly after this, there is an entry

  -VPN-RADIUS-GP is denied access

  where VPN-RADIUS-GP is the name of the tunnel group policy in my ASA.

  Ive tried a lot of literature and a few forums and have not yet find any explanation as to why this would happen as username trying to authenticate to the ISA

  Anyone have any ideas?

  Thank you

  group-policy VPN-Radius-GP external server-group VPN_Radius_Auth password aaaaaaaaaaaaaaaaaaaaaa

  It is a group-foreign policy, by definition, that it is defined on the AAA server group policy, so the ASA sends a radius access request to retrieve the attributes of group policy.

  See for example http://www.cisco.com/en/US/docs/security/asa/asa72/configuration/guide/vpngrp.html#wp1133706

  If this isn't what you want, then just remove the group policy and use internal (as the "q101 VPN GP" you).

• Client VPN authentication question

  Hi friends,

  I recently started a new company, where the Cisco VPN Client is used by all remote Windows users. I'm not familiar with the customer. I see by our remote access policy that clients authenticate using PAP. This immediately caught my concern.

  My question is if this poses a threat to security? Even if the authentication is not encrypted, it is always the case in a 3DES IPSec tunnel, right? What is the best practice regarding using the VPN client and authentication?

  Thanks in advance!

  Equipment:

  Cisco VPN Client v5 (latest version) on Windows XP SP3

  Microsoft IAS (RADIUS) on W2K3 Server R2 x 64

  Router Cisco 3825

  IOS 12.4.24T Adv IP Services

  If I understand your customer VPN ends on 3825 router. the customer gets the name of username/password prompt after than phase 1 so it may not be clear.

  I hope this helps

• Recommendations for VPN authentication

  So, now that Cisco has helped me get the vpn works on my ASA 5525-X I need to use an active administrator for the authentication/grouping of customers for several profiles in anyconnect.

  My question is what is the simpler and more effective way of setting this up. I have a R2 2012 NAP server that is used to authenticate the AD users for access to the switches. But should I use that for ASA as well or can I use AD directly to the ASA?

  A reminder to those who have not seen my posts, I'm very new to the ASA and the need to get this up and running quickly... Any help/suggestions would be greatly appreciated.

  Thank you

  Stacey

  Hi Stacey,

  You can use the Windows Server direct to the ASA, it uses the LDAP protocol. You will need to implement the ASA like this:

  AAA-Server LDAP-SRV protocol ldap
  AAA-Server LDAP-SRV (inside) host XXXXXXXXX--> IP address of the server
  LDAP-base-dn DC = vpn, DC = also, DC = com--> where users are stored
  LDAP-connection-dn CN = ASA-LDAP-user, CN = Users, DC = vpn, DC = also, DC = com--> the entire AD tree.
  LDAP-login-password *--> the administrator password
  LDAP-naming-attribute sAMAccountName
  LDAP-scope subtree
  microsoft server type

  Now, you need to get the login DN: and the base dn. Now on the ad, you need to create several user groups and divide the users for different levels of authorization as: salespeople, employees...

  You can test the authentication by using this command:

  test the aaa server for authentication LDAP_SRV host XXXXXX username: password XXXXX: XXXX

  and then see if it fails, then you can solve the problem

  You can then configure the mapping of LDAP attributes to MAP a group of users on the server of advertising to a group policy on the SAA.

  I would like to know how it works!

• SSL VPN authentication using different sequences of identity Sources

  Morning,

  At the moment we have SSL VPN configuration passing security to GBA. This is accomplished by using strong authentication. GBA the

  Sequence identity Sources is WBS then AD.

  We want to implement on the same firewall a few users select proper respect by AD authentication, they will have a group name different tunnel connecting etc.

  GBA im not sure how I would setup two sequences of Sources Identidy therefor using the same Service selection rule. At the moment I have if RAY and IP is XXX then political use of XXX

  If it's confusing that I can extend were nesscessary
  Thank you

  Hello

  I don't know how it looked like GBA but on its flexible ISE

  If the rule is simple

  If the RADIUS request is device ASA type formed then check the tunnel-group-name attribute (146) and will benefit from its interventions to the string value choose LOCAL or AD store.

  

  hope this helps

• PIX VPN authentication

  I see options to authenticate users VPN on Radius, Ganymede +, local or using a VPN group. Is - this from there anyway to authenticate on a NT domain, Active Directory by Microsoft or Novell eDirectory directory service?

  Cannot find details in the configuration guide.

  Thank you

  Greg

  Hello Greg,.

  Thanks for your question. In fact, PIX is not built in API unlike VPN 3 K to send the authentication request directly to the devices you mentioned. PIX has the RADIUS / Ganymede + API and that is why its need to use an AAA server that supported Radius/Ganymede. AAA Cisco Secure Server can be integrated with all deviecs you mentioned. You can point your PIX to the Cisco Secure AAA server and he will forward the application to the database you mentioned in your post.

  I hope this helps. Kind regards

• LOCAL + RSA VPN authentication?

  Hi... we have a customer using an ASA 5520 8.2 (2) for VPN (webvpn) connections. Currently, they use the user/pass configured locally for authentication (it's a default, there is no explicit LOCAL configuration).

  They would use their RSA security device, but not for all users at once. Is it possible to use the local database and RSA as points of authentication, i.e. If there is no configured local user name, try the RSA (or vice versa)?

  Thank you

  Jim

  The ASA can do that natively the emergency authentication being quite limited on the SAA. Two possibilities are there to solve this:

  (1) use an external server which can chain these authentication stores (ACS or ISE may be used). But it is a rather expensive solution.
  (2) build more tunnel-groups with different authentication settings and ask your users to use a particular.

• SSL VPN authentication using RADIUS

  I am running version ASA 8.4 (1) and anyconnect version 3.0.1047. My SSL VPN works great, but I encountered a problem with a user. his story did not work, and each time users had this message ""VPN server could not parse request '. "

  I found the problem after getting user information, which means that his user name and password. Had a password '&' as one of the special characters. When we change to something that isn't that it works very well.

  We use the NPS as RADIUS server. but when I run a test within the CLI, it works fine, only when anyconnect requests to authenticate, he fails.

  Someone at - it had the similar problem?

• Authentication of ISE 1.3 VPN with Email address instead of the username

  Hello

  I would like to set up a VPN authentication against LDAP Microsoft Directory.

  The user must between its e-mail address that is stored in the mail attribute LDAP MSFT. How can I configure ISE to watch in the mail of the attribute to find a user rather than the user name?

  Thanks in advance

  Alex

  You can use the "custom" setting schema in ISE under the external identity/LDAP and change the object attribute to "mail" instead of "samAccountName", which is the normal attribute ISE uses to search for users in the LDAP structure. You can then chech if it works, by going to the menu attributes and search for an e-mail address that you know should be there.

  Hello

  An IP address assignment is not possible the GBA. However, you can configure the simple vpn authentication.

  GBA:

  access policies> default network address> identity(select internal users or if its AD then select AD) > authorization > click on customize > move the desired condition>
  
  for example> device ip address> put in the ip address of ASA(vpn device)> authorization profile> permit access.
  
  so it will be>
  access policy> default network access> identity(internal users or AD)> authorization > create rule> device ip=1.1.1.1 > authorization profile=permit access

• Replication failover PIX VPN (CEP) certificate

  Hello

  Had a pair of PIX 525 on 6.3 (4) version running in active/failover mode, I recently configured VPN authenticated by certificates, which involved the use of PRACTICE in order to get the certificate to the PIX. Certificates have been imported for the PIX from a snap-in with the software component CEP Protocol Windows CA server by following the instructions described here: http://www.ciscosystems.com/en/US/docs/security/pix/pix63/configuration/guide/sit2site.html#wp1007263 .

  It all works very well, the configuration has been saved, certificates registered cases using "ca save all", everything works well except the certificates that have been imported have not been replicated for the PIX failover - the command 'Show the ca certificate', shows not all certs.

  Private keys show 'sh ca mypubkey rsa' are the same on both devices.

  I'm not able to find any documentation about how certificates must be replicated on the PIX failover, and it is not possible to write certificates again on the PIX failover using the commands they were initially imported by:

  PIX - fw # conf t
  WARNING *.
  Configuration of replication is NOT performed the unit from standby to Active unit.
  Configurations are no longer synchronized.

  PIX - FW (config) auth ca ca
  WARNING *.
  Configuration of replication is NOT performed the unit from standby to Active unit.
  Configurations are no longer synchronized.

  Everyone knows a similar issue or how to get the PIX failover with the new ca certificates?

  Kind regards

  Sarunas

  Hello Sarunas

  PIX 6 indeed do not synchronize keys and certificates automatically.

  However, you should be able to do this first, forcing a failover (i.e. secondary image make it active), then register (now active) high school with the certification authority.
