LDAP AAA for VPN configuration

Preface: I'm all new to Cisco Configuration and learn as I go.

I'm at the stage of configuration LDAP to configure a VPN on ASA 5520, software release 8.3 (1).  Previously the programme installation and RADIUS authentication successfully tested, I tried to use similar logic to implement the LDAP authentication/authorization.  I have acquired a service account that queries the pub for the identification of the registered user information.  My main resource was the following Manual: Cisco ASA 5500 Series Configuration Guide using the CLI Software Version 8.3.  I did initially configurations by using ASDM, but could not get tests to succeed.  So I amazed the ASDM configs and went to the CLI.  Here is the configuration.

AAA-server AAA_LDAP protocol ldap
AAA-server host 10,20,30,40 (inside) AAA_LDAP
Server-port 636
LDAP-base-dn domain.ad
LDAP-scope subtree
LDAP-naming-attribute uid
LDAP-login-password 8 *.
LDAP-connection-dn cn = commonname, OU = ou01, or = ou02, dc = domain, dc = ad
enable LDAP over ssl
microsoft server type
LDAP-attribute-map LDAP_ATTRIB

---

type tunnel-group ASA_DEFAULT remote access
attributes global-tunnel-group ASA_DEFAULT
authorization-server-group AAA_LDAP

---

LDAP attribute-map LDAP_ATTRIB
name of the MemberOf IETF Radius-class card
map-value MemberOf "VPN users' asa_default

---

I tested all the naming-attribute ldap alternatives listed with the same results.

When I test the authentication using this configuration, I get the following error: ERROR: authentication server does not: AAA Server has been deleted

When I test authorization using this Setup, I get the same error (except for the word permission instead of authentication).

I am at a total loss.  Any help would be appreciated.

I would use ldp.exe to see if you can make sure that the sytnax of your ldap-connection-dn is just as you have in your config, it really helps just copy and paste.

The problem I see is the following:

[210] link as st_domadm
[210] authentication Simple running to st_domadm to 10.20.30.30
[210] simple authentication for st_domadm returned credenti invalid code (49) als
[210] impossible to link the administrator returned code-(1) can't contact LDAP er

I suppose your ldap-connection-dn is st_domadm and you try to test with the administrator account?

Thank you

  • AAA for VPN - Kerberos, LDAP or an NT domain?

    All,

    After that a small return on what you think is the best method for AAA authentication for VPN clients when authenticating against a Windows domain for remote access?

    I have always used "NT Domain" because it seems to correspond roughly to the NT Auth I used to use on the old hubs. However, I (finally) decided to take a look at the Kerberos and LDAP, since they must have been added for a reason...

    Far as I can tell LDAP adds the ability to search a little more finely (basic DN) AD, but that's all. Am I missing something? Are there more reason to use LDAP or Kerberos domain auth?

    What is more reliable? That you guys use?

    See you soon!

    Either it is reliable, you can map users in different group policies or apply different DAP political, based on their belonging to a group. If you are basic authentication, then your method is still the best way to go.

    Thank you

  • New ASA 5545 x for VPN configuration

    The ASA has an IOS disk0: / asa911-smp - k8.bin.

    In the process of reconfiguration of cryptography groups card and tunnel, I am now giving the key word of iKev1 or iKev2.

    I am considering the ikev2 as being safer, but would like some clarification and advice on which to choose and why?

    Please inform promptly.

    IKEv2 is in many ways superior. Both ends must have the level of code to support - that is about the only negative.

    There are a few good tips and advice on why IKEv2 can be your best choice in this document to TAC.

  • CIsco Anyconnect VPN with LDAP AAA

    Hi there, I was hoping that someone can point me in the right direction here. I created a VPN connection profile to match anyconnect SSL entering customers. I would like to use LDAP group membership as a sine qua non for authentication. I found a few online pages on what to do about it, I followed. Unfortunately, it seems my connection profile to allow access to any user in the ldap, not only those of the ldap group database. I'll post the relevant bits of the config here in hopes that someone can point my mistake!

    The idea of the config is to have the map of connections 2 by default a noaccess policy which has 0 simultaneous connections and the profile card (SSL_VPN) connection ssl to anyconnect to group_policy_SSL_VPN group policy.

  • Can the NAT of ASA configuration for vpn local pool

    We have a group of tunnel remote ipsec, clients address pool use 172.18.33.0/24 which setup from command "ip local pool. The remote cliens must use full ipsec tunnel.

    Because of IP overlap or route number, we would like to NAT this local basin of 172.18.33.0 to 192.168.3.0 subnet when vpn users access certain servers or subnet via external interface of the ASA.  I have nat mapping address command from an interface to another interface of Armi. The pool local vpn is not behind any physical interface of the ASA. My question is can ASA policy NAT configuration for vpn local pool.  If so, how to set up this NAT.

    Thank you

    Haiying

    Elijah,

    NAT_VPNClients ip 172.18.33.0 access list allow 255.255.255.0 10.1.1.0 255.255.255.0

    public static 192.168.33.0 (external, outside) - NAT_VPNClients access list

    The above configuration will be NAT 172.18.33.0/24 to 192.168.33.0/24 when you go to 10.1.1.0/24 (assuming that 10.1.1.0/24 is your subnet of servers).

    To allow the ASA to redirect rewritten traffic the same interface in which he receive, you must also order:

    permit same-security-traffic intra-interface

  • Two links one for VPN Site to Site and another for internet on the same router configuration

    Hi all

    I have 2 internet links an ADSL and lease terminated on the same router. I need to configure ADSL for VPN site-to-site of HO and internet leased line dedicated for all users.

    my site IP subnet is 10.10.100.0/24 and HO subnet is 10.1.0.0/24.   Please find attached Config and advice it will be OK and works fine

    Thanks in advance...

    Mikael

    Hello

    For me, it looks like it has configured the route correctly;

    ip route 0.0.0.0 0.0.0.0 fastethernet4 -> for all traffic to the internet.

    Road 10.1.0.0 ip 255.255.255.0 Dialer1 -> for vpn traffic to HO.

    The public_IP_HO must be defined according to the map of encryption using the set by the peers command.

    I want to add is on the isakmp policy hash attribute, you can choose between sha/md5 or whatever available on your device. Make sure that the isakmp policy to match political isakmp of your HO.

    The other thing is the acl for the internet. You may want to consider replacing the deny statement if you want to deny traffic only to your jar currently it is said to deny all traffic 10.10.100.0 10.0.0.0 network, not to the 10.1.0.0 HO (network).

  • 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!

  • Traffic permitted only one-way for VPN-connected computers

    Hello

    I currently have an ASA 5505.  I put up as a remote SSL VPN access. My computers can connect to the VPN very well.  They just cannot access the internal network (192.168.250.0).  They cannot ping the inside interface of the ASA, nor any of the machines.  It seems that all traffic is blocked for them.  The strange thing is that when someone is connected to the VPN, I can ping this ASA VPN connection machine and other machines inside the LAN.  It seems that the traffic allows only one way.  I messed up with ACL with nothing doesn't.  Any suggestions please?

    Pool DHCP-192.168.250.20 - 50--> for LAN

    Pool VPN: 192.168.250.100 and 192.168.250.101

    Outside interface to get the modem DHCP

    The inside interface: 192.168.1.1

    As we change the config I would do as well as possible.

    First, it is strongly recommended to use a different range of IP addresses for VPN clients and the internal network

    No VPN_Pool 192.168.250.100 - 192.168.250.101 255.255.255.0 ip local pool mask

    A few things to change:

    (1) pool of IP must be a single subnet, it is not the same subnet as your subnet internal.

    (2) your NAT ACL 1 must be changed to ACL extended for you can configure NAT exemption, so if your pool is reconfigured to be 10.10.10.0/24:

    access-list 120 deny ip 172.17.0.0 0.0.255.255 10.10.10.0 0.0.0.255

    access-list 120 allow ip 172.17.0.0 0.0.255.255 everything

    overload of IP nat inside source list 120 interface GigabitEthernet0/1

    No inside source list 1 interface GigabitEthernet0/1 ip nat overload

    (3) OUT POLICY need to include VPN traffic:

    access-list 121 allow ip 10.10.10.0 0.0.0.255 172.17.0.0 0.0.255.255

  • VPN configuration blocking Internet connectivity

    I own an iPhone6 (bought in November 14 and another iPad4 (bought in early 2014) - I face a problem even in both devices.)

    Whenever I'm trying to be devices connecting to the Internet (this either through Mobile or wireless data, I have to take concrete steps to start-up the VPN setting without which the device connect to the Internet. However sometimes (although not very often) the VPN configuration gets turned on by itself without manual intervention (on start-up or mobile data or WiFi on the device). So there is always some delay time in the connection to the Internet whenever I want to use the device.

    I would be grateful for suggestions from the community in order to overcome the problem.

    You have installed VPN software or you have configured in your VPN settings? If you have a VPN configuration, then check its configuration. If you do not have a VPN configuration or a VPN software installed, then the VPN switch in settings should not illuminate.

  • You don't have enough privileges for the configuration of the connection properties. Contact your administrator

    When you attempt to connect to the VPN Aventail I get th e following in a "Connection error" message box: "you don't have enough privileges for the configuration of the connection properties. Contact your administrator. That this connection has worked before. I suspect a MS patch for breaking it. Any help would be appreciated.

    We have solved the problem yesterday, by simply reinstalling the Aventail software.

    I spoke to network administrators and nothing had changed, so it's quite strange.

    anyway thanks a lot for your help Brian.

    See you soon,.

  • Clustering for VPN site-to-site VPN concentrator?

    Hi all

    I think the grouping of the Concentrator VPN configuration guide is only good for the VPN site-to-customer, that is to say that the grouping option cannot be deployed in VPN site-to-site of HA and load balancing?

    Thank you and best regards,

    MAK

    OK, the function was only ever for clients of SW and HW, not the L2L tunnels.

    L2L tunnels, you can configure the settings of tunnel on two of the hubs of the cluster and then just "defined by peer" two statements under the card encryption of the remote device, these statements point to each of the specific IP addresses hubs (not the cluster address).

    Does not give you true balance as do customers SW, but it gives you redundancy.

  • Backup AAA for PIX

    I have a PIX with the following configuration:

    GANYMEDE + Protocol Ganymede + AAA-server

    AAA-server GANYMEDE + (inside) host 192.168.1.1 77777 timeout 5

    RADIUS Protocol RADIUS AAA server

    AAA-RADIUS (inside) host 192.168.1.1 Server 77777 timeout 10

    AAA-server local LOCAL Protocol

    AAA authentication GANYMEDE serial console +.

    AAA authentication enable console GANYMEDE +.

    order of AAA for authorization GANYMEDE +.

    AAA accounting correspond to aaa_acl inside RADIUS

    Everything works fine when the RADIUS server is available. When he is not available, I can log in with the username "PIX" and "password". The problem is, once I connected, I can't get permission to execute orders. Does anyone know of a command that is similar to the "if-certified" for routers that I can use?

    There is no method of backup for authorization for the PIX. As you know, if the RADIUS server is down, you can connect with "pix" and the password enable, but it doesn't help a permission. The only thing you can do is wait the GANYMEDE server back to the top. I'm sorry.

  • ICPPX 4.05 and/or call Mgr 4.13 multiple LDAP servers for redundancy

    We run IPCCX 4.05 to high availability (active / standby) and Call Manager 4.13 Pub/Sub. In this configuration, we use LDAP for authentication AD instead of the directory of DC (not my choice... things you inherit in life).

    The call of Bishop and/or the servers IPCCX can be setup to point to multiple LDAP servers for redundancy?

    CAN CM 4.13 and/or IPCCX 4.05 LDAPS support (as I have said, things you inherit)?

    Our sysadmin team won our main server to the DC, and with him all functins LDAP search broke. Needless to say they will be put in place of LDAP or LDAPS on our main and backup DC in the near future.

    Any information/suggestions/recommendatinos are appreciated.

    Thank you

    Hello

    This IS possible.

    If the CRS web interface admin (/ appadmin) is available:

    1. open a session

    2. go to the system > LDAP information

    3 type the FQDN / IP addresses (I recommend the latter) for LDAP servers, separated by commas (for example, I have something like in our laboratory: "ldapserver.domain.as, 10.1.1.1" - works like charm)

    4. a window will appear asking if the LDAP information must be created or you just want to add another LDAP server (~ configuration already there). Choose wisely :-)

    5. restart the server. No, restart the CRS engine is not enough.

    If the CRS web administration interface is not available (~ as you said Mr. Sysadmin won DC backend), the there is a chance to get rid of this guy ;-) Anyway, there is always a chance that you can make it work. Of course, the LDAP server must already contain the appropriate configuration.

    1. connect to the CRS Server using rdesktop/VNC

    2. look for this file: C:\Program Files\wfavvid\properties\directory.properties it's just a plain text file. Look for this CCNIniFile=c:\\winnt\\system32\\ccn\\ccndir.ini

    In fact, it can be something else too, this is the default path.

    3. this file contains the information that we are looking for: LDAPURL 'ldap://10.1.1.1:389, ldap://10.1.1.2:389' and other important things like passwords and base DN

    Change it according to your needs. :-)

    4. restart the server.

    Good luck.

  • RV042 VPN configuration

    I'm looking for help to the RV042 configuration for VPN access to local machines and Win 2008 Server.  History: had problems with remote printers created for customers log into old Linksys RV042 VPN Linksys software.  First Tech exposed server without security, and it had to be removed because he was attacked, but did not print problem.  2nd tech failed to get VPN to work after 1 tech.  3rd tech 4hours and I got the router is a piece of...  I am so on more than 1000 and unable to have a simple router put in place.  The current situation.  New RV042 with the V4.1.1.01 firmware, using the Cisco VPN client 5.0.07.0410, most of the 32-bit machines on network XP, a 64-bit win 7.  My customers do not have access to their data for too long and I need a quick fix.  Willing to pay, just the person to really know what they are doing.  Thanks in advance.  (I hope its ok to offer to hire someone!)

    Mike,

    I am sorry to hear that you're having these problems and even more sorry to tell you that you have problems with the client VPN Cisco 5.x because the RV042 does not support this VPN client. Cisco VPN client is an enterprise-level software utility that uses the IPsec protocols to connect. What you should use is Cisco VPN fast. Cisco VPN client authenticates in 2 phases while the RV042 and Cisco Qvpn authenticates in 1 phase. The router doesn't understand just how to manage connections from the Cisco VPN client. I've included a link to the Cisco Qvpn utility below. Hope this helps
