Multiple domains authentication on Cisco ISE

Hi,
Does the current Cisco ISE supports for authenticating on multiple Active Directories ?
I can only set Cisco ISE to join on single active directory and LDAP
Does anyone have set Cisco ISE to support EAP-FAST with WPAD or PAC provisioning ?
Thanks

Hi,
We are into a situation where we need to authenticate users of two domains and these two domains are completely independent (no common DNS server). ISE is not able to resolve one of the domain using the DNS server settings and Adding a host entry for the domain name is not sufficient since Kerberos, GC and LDAP SRVs need to be resolvable as well.
From what I know ISE 1.3 should supports disjointed domains and there is no requirement for ISE to have 2 way trust relationship with domains.
Please share your experience if someone has faced similar situation before.
Regards,
Akhtar

Supplicant doesn`t pop up on Win XP during authentication wth Cisco ISE

Hello!
I try to configure 802.1X authentication with Cisco ISE, Win XP SP3 and native supplicant.
Problem is that when workstation connects to the network, it uses hostname as an username and sapplicant doesn`t pop up to ask me username and password. Anybody know how to resolve this problem? Mb to install some patch on Win XP?
Thank you!
BR,
Max

Tarik, yes of course. Also I manually installed Cisco NAC agent on workstation and it also don`t ask credentials.
I read this article, but I don`t understand what should I do?
In RADIUS debug I see folowing:
RADIUS(000000F7): Send Access-Request to ISE:1812 id 1645/243, len 248
RADIUS: User-Name           [1]   29 "host/ISEfuji.office"
RADIUS: NAS-Port-Id         [87] 22 "GigabitEthernet1/0/1"
RADIUS: NAS-IP-Address      [4]   6   192.168.244.252
Why User-Name is workstation hostname I don`t understand.

AD Machine Authentication with Cisco ISE problem

Hi Experts,
I am new with ISE, I have configured ISE & Domain computers for PEAP authentication. initially machine gets authenticated and then starts going MAB.
Authentication policy:
Allowed protocol = PEAP & TLS
Authorization Policy:
Condition for computer to be checked in external identity store (AD) = Permit access
Condition for users to be checked in external identity store (AD) plus WasMachineAuthenticated = permit access
All of the above policies do match and download the ACL from ISE but computer starts to mab authentication again...
Switchport configuration:
===============================================
ip access-list extended ACL-DEFAULT
remark Allow DHCP
permit udp any eq bootpc any eq bootps
remark Allow DNS
permit udp any any eq domain
permit ip any host (AD)
permit icmp any any
permit ip any host (ISE-1)
permit ip any host (ISE-2)
permit udp any host (CUCM-1) eq tftp
permit udp any host (CUCM-2)eq tftp
deny ip any any
===============================================
switchport config
===============================================
Switchport Access vlan 10
switchport mode access
switchport voice vlan 20
ip access-group ACL-DEFAULT in
authentication open
authentication event fail action next-method
authentication event server dead action authorize vlan 1
authentication event server alive action reinitialize
authentication host-mode multi-domain
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication periodic
authentication timer reauthenticate server
authentication timer inactivity 180
authentication violation restrict
mab
dot1x pae authenticator
dot1x timeout tx-period 100
====================================================
One more problem about the "authentication open" and default ACL. Once the authentication succeeds and per user is ACL pushed though ISE to the switch. The default ACL still blocks communication on this switchprort.
Your help will highly appreciated.
Regards,

You need to watch the switch during an authentication, see if the machine is passing authentication and the user may be failing authentication causing the switch to fail to mab. If your switch configuration is on auth failure continue to next method, then this makes sense. The question is why is the user failing auth but the machine is passing, could be something in the policy. Make sure your AD setup has machine authentciation checked or it may not tie the machine and user auth together and the user may be failing because ISE can't make that relationship so the machinewasauth=true is not beeing matched. Easy way to check is remove that rule from your policy and see if the same thing happens.
I've also seen this happen when clients want to use EAP-TLS on the wired, machines passes auth, then the user logs into a machine for the first time. The user auth kicks off before the user gets a cert and fails auth with a null certificate, since this is a auth failure the switchport kicks over to MAB.
I don't think wasmachineauth=true is that great, I prefer to use EAP-FASTv2 using Cisco Anyconnect NAM with eap-chaining. This is great because you can do two part authentication. EAP-FAST outer with EAP-TLS inner for the machine auth, and MSCHAPv2 for the inner of the user auth. You get your EAP-TLS auth for the machine and don't have to worry about a user logging into a machine for the first time and switching to MAB because the user doesn't have a cert yet. I also do my rule to say if machine pass and user fail, then workstaion policy, if machine and user pass then corp policy.

Strip multiple @domain used in username on AD Integration with Cisco ISE?

Hi there ,
How to strip multiple domain suffixes from username through ISE with AD being used as external Identity Source. Username is being used in username@domain format.
Cisco ISE 1.2 patch 4 introduced strip prefix or suffix @domain realm from username through ISE with AD being used as external Identity Source. But the documentation is not updated for this feature. I am able to strip 1 domain suffix successfully but subsequent ones listed in the suffix list fails to get stripped.
Any thoughts on the same.
Thanks Kumar

In the ISE Under Administration > Identity Management > External Identity Sources
Choose Active Directory on the Left, Select your AD Server and select Advanced Settings
Under Identity Suffix Strip, Make sure Strip prefixes listed below: is selected (I know, it says prefix).
In the List of Suffixes box, enter your list of domain suffixes to strip. The separating character is a comma (,).
If this doesn't fix your issue, then I am afraid that a call to TAC may be in order.
*****UPDATE*****
Spaces are significant characters. When listing domains, do so as such:
@domain.com,@domain.local,@testdomain.com
*****END UPDATE*****

Cisco ise 1.2 install certificates for ise cluster question

hello all i have an ise cluster of 4 devices. 1 primary admin/secondary monitor, 1 secondary admin/primary admin and 2 policy nodes
i need to install public CA certs on them. can I generate 1 CSR on one of the nodes, that includes a SAN with the DNS names of all the nodes?
Therefore get only 1 cert from the CA, and export and import the same cert into all the other nodes?
or do i have to generate 1 CSR for each node and purchase 4 certs? Wild card certs is not an option. tHANKS,

ISE allows you to install a certificate with multiple Subject Alternative Name (SAN) fields. A browser reaching the ISE using any of the listed SAN names will accept the certificate without any error as long as it trusts the CA that signed the certificate.
The CSR for such a certificate cannot be generated from the ISE GUI. http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine-software/113675-ise-binds-multi-names-00.html
Cisco ISE checks for a matching subject name as follows:
1. Cisco ISE looks at the subject alternative name (SAN) extension of the certificate. If the SAN contains one or more DNS names, then one of the DNS names must match the FQDN of the Cisco ISE node. If a wildcard certificate is used, then the wildcard domain name must match the domain in the Cisco ISE node's FQDN.
2. If there are no DNS names in the SAN, or if the SAN is missing entirely, then the Common Name (CN) in the Subject field of the certificate or the wildcard domain in the Subject field of the certificate must match the FQDN of the node.
3. If no match is found, the certificate is rejected.

Cisco ISE - EAP-TLS - Machine / User Authentication - Multiple Certificate Authentication Profiles (CAP)

Hello,
I'm trying to do machine and user authentication using EAP-TLS and digital certificates. Machines have certificates where the Principal Username is SAN:DNS, user certificates (smartcards) use SAN:Other Name as the Principal Username.
In ISE, I can define multiple Certificate Authentication Profiles (CAP). For example CAP1 (Machine) - SAN:DNS, CAP2 (User) - SAN:Other Name
Problem is how do you specify ISE to check both in the Authentication Policy? The Identity Store Sequence only accepts one CAP, so if I created an authentication policy for Dot1x to check CAP1 -> AD -> Internal, it will match the machine cert, but fail on user cert.
Any way to resolve this?
Thanks,
Steve

You need to use the AnyConnect NAM supplicant on your windows machines, and use the feature called eap-chaining for that, windows own supplicant won't work.
an example (uses user/pass though, but same concept)

Cisco ISE multiple EAP authentication methods question

With Cisco ISE can you have various clients each using different EAP methods, such as PEAP for Windows machines, MD5 for legacy and TLS for others?
My current efforts seem to fail as if a device gets a request from the ISE for an EAP method it doesnt understand it just times out.
Thanks in advance.

Multiple EAP Methods work fine. If your Clients are being crap you could try forcing then to use a specific set of Allowed Authentication Method by creating more specific Authentication rules.

Cisco support LDAP Authentication - Multiple Domains

Hi,
I want to change the LDAP authentication as the multiple domains and my Windows AD environment is the child trust, that mean the root DC is the "abc.com", which have the two child DCs, e.g. "us.abc.com ", "uk.abc.com"
Is it possible I just changed the LDAP auth. with user search space as the root DC is fine?
OR
I must use the "userPrincipalName" ?

But it had the collision SAMAccountName, that would have the same account name between the us.abc.com and uk.abc.com.
If I changed the "userPrincipalName" LDAP sync to CM, how about the Jabber login?

Cisco ISE - multiple AD - trust relationships

Hello,
I have a customer who has multple AD forests and an ISE deployment running 1.1.3.
The customer scenario is as follows - there is an Internal AD forest (internal users) and an External AD forest (external users such as consultants). The objective is to use Cisco ISE to authenticate and authorize the users in both AD forests. CIsco ISE is connected to the Internal AD forest.
We know that multiple AD support is coming in 2014 with versioon 1.3 - other options such as LDAP/EAP-TLS are not a viable option for the customer.
1.       Currently – the Internal AD forest has an External, Non-transitive – one-way trust with the External Forest
     a.       The objective here is to use a feature called Selective Authentication in order to filter the outgoing requests from the External Forest to the Internal Forest – this is a selective trust feature that can be used to control access to specific resources in Internal Forest and for authentication between Internal/External Forest via Cisco ISE
     b.      Preliminary testing has shown that a one way trust seems to work for Cisco ISE authentication/authorization
     c.       Further testing is underway to test the Selective Authentication feature (ie restrict access to specific resources etc…)
Question : has any one used this and is this a supported method by Cisco (I know they mention a mutual trust relationship is required)?
2.       We are exploring a second scenario - the Internal AD forest will have an External, Non-transitive – two-way trust with the External Forest
     a.       Same objectives as in 1 – we would attempt to use the Selective Authentication in the following fashion (this is an example)
          i.      External Forest has outgoing filter to allow access to specific resources in Internal Forest, and for authentication
          ii.      Internal Forest has incoming filter to deny access to all resources in External Forest
In this case we would filter so it resembles a 1 way trust relationship - anyone try this, anyone know if this would be a supported method by Cisco?
Thanks in advance for your replies.
Robert C.

Cisco has published a nice new guide on Active Directory integration with ISE 1.3. As noted there:
"Cisco ISE can connect with multiple Active Directory domains that do not have a two-way trust or have zero trust between them. Active Directory multi-domain join comprises a set of distinct Active Directory domains with their own groups, attributes, and authorization policies for each join."
I've setup one such deployment just recently and found it quite simple to just add the second domain and use it an en external identity source accordingly.

Cisco ISE auth policy based on Active Directory domain membership

I am currently testing the Cisco ISE product and I am trying to find a way to assign an authorization policy based on domain membership. Our company sorts standard users and project team member into different domains so it seemed like the ideal thing to sort with. Unfortunately, I am no AD expert and there are a mind boggling number of conditions/expressions to choose from. I figured I would be the first person to try this. What have other done to solve this problem?
I have tried using the memberOf attribute and matching to .*(domain).* Basically looking to see if memberOf contains the domain name. It works for machine authentication, but when I log it the system cannot find my account info for some reason and boots me to the guest vlan.
Thank you.

Are the two sets of users actually residing on two separate and independent domains? If so then that is probably where your problem is as ISE can only integrate with a single domain. If you have multiple domains then there must be a trust relationship between them. Another solution is to use LDAP integrations as there is not a limit with LDAP integrations.
Thank you for rating!

Cisco ISE 1.2 and 2 Active Directory Domains

Hi Support,
does anyone know whether I can perform Certificate Authentication for two different Active Directory domains using the same ISE host / deployment?
We have two forests with a trust link between them.
We have a seperate PKI in each domain.
I am thinking that the ISE can only be joined to a single domain, but because we have a trust between the two forests, the ISE can have two certificate profiles in an identity source sequence which can then use in a single authorisation policy.
I take it that I would need local certs from each CA in the local certificate store of the ISE?
We are performing a company merger and we cannot migrate users to the primary AD domain due to several reasons so we would like to use the same ISE deployment to authenticate Wireless users on both AD domains.
Thanks
Mario

Mario,
This is possible. Here are the guidelines for the Multi-Forest support in ISE 1.2:
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/user_guide/ise_user_guide/ise_man_id_stores.html#pgfId-1350874
You would have to set a new Certificate Authentication Profile for each domain and use the Authentication Policies to determine which of the Certificate Authentication Profiles to use.

Cisco ISE AD (Windows Server 2013) Authentication Problem

Background:
Deployed two Cisco ISE 1.1.3. ISE will be used to authenticate wireless users, admin access to WLC and switches. Backend database is Microsoft AD running on Windows Server 2012. Existing Cisco ACS 4.2 still running and authenticating users. There are two Cisco WLCs version 7.2.111.3.
Wireless users authenticates to AD through ACS 4.2 works. Admin access to WLC and switches to AD through ISE works. Wireless authentication using PEAP-MSCHAPv2 and admin access wtih PAP/ASCII.
Problem:
Wireless users cannot authenticate to AD through ISE. The below is the error message "11051 RADIUS packet contains invalid state attribute" & "24444 Active Directory operation has failed because of an unspecified error in the ISE".
Conducted a detailed test of AD from ISE. The test was successful and the output seems all right except for the below:

Action Taken:
Log on to Cisco ISE and WLC using AD credentials. This rules out AD connection, clock and AAA shared secret as the problem.
2)     Tested wireless authentication using EAP-FAST but same problem occurs.
3)     Detailed error message shows the below. This rules out any authentication and authorization polices. Before even hitting the authentication policy, the AD lookup fails.
12304 Extracted EAP-Response containing PEAP challenge-response
11808 Extracted EAP-Response containing EAP-MSCHAP challenge-response for inner method and accepting EAP-MSCHAP as negotiated

15006 Matched Default Rule
15013 Selected Identity Store - AD1
24430 Authenticating user against Active Directory

4)     Enabled AD debugging logging and had a look at the logging. Nothing significant and no clues to the problem.
5)     Tested wireless on different laptos and mobile phones with same error
6)     Delete and add again AAA Client/Devices on both Cisco ISE and WLC
7)     Restarted ISE services
8)     Rejoin domain on Cisco ISE
9)     Checked release notes of ISE 1.1.3 and WLC 7.2.111.3 for any open caveats. Nothing found related to this problem.
10)    There are two ISE and two WLC deployed. Tested different combination of ISE1 to WLC1, ISE1 to WLC2 etc. This rules out hardware issue of WLC.
Other possibilities/action:
1)     Test it out on a different WLC version. Will have to wait outage approval to upgrade WLC software.
2)     Incompatibility of Cisco ISE and AD running on Microsoft Windows Server 2012
Anyone out there experienced something similar of have any ideas on why this is happening?
Thanks.
Update:
1) Built another Cisco ISE 1.1.3 sever in another datacentre that uses the same domain but different domain controller. Thais domain controller is running Windows Server 2008. This works and authentication successful.
2) My colleague tested out in a lab environment of Cisco ISE 1.1.2 with Windows Server 2012. He got the same problem as described.
This leads me to think there is a compatibility issue of Cisco ISE with Windows Server 2012.

Does anyone know if ISE 1.1.3 p1 supports AD DCs running 2012, if not which patch is required ot version?
Worryingly when ISE joins a 2012 DC it states it's connected successfully, and if another 2003 DC is available in that datacentre it will perform the auths against that DC whilst actually advertising (Connections in the GUI) that it's connected to the 2012 DC. We ended up mapping 8 PSN IP’s to another datacentre which has one Win2003 servers whilst the old 2003 DC is being promoted back, the 8 ISE servers started working, even though they still advertised they were connected to the 2012 DCs in the original datacentre - I performed a leave and join on one PSN and only then did it advertise that the node was connected to a DC in a different datacentre

Strip @domain on LDAP Integration with Cisco ISE?

Hi there ,
I got a WLC conntect with a Cisco ISE. There are two SSID authenticated against the ISE.
One SSID has AD-Integration as External Identity Source, the other SSID is authenticated through LDAP.
Authentication ist working fine.
When an user authenticates through LDAP, he/she has to enter "username@domain". The protocol is EAP-GTC.
How can I change the ISE that the user has only to enter "username" and the "@domain" part ist already set on the ISE?
Thansk a lot,
Norbert

From the user guide it seems that LDAP only allows you to strip the prefix/suffix and can't add the suffix.
http://www.cisco.com/en/US/docs/security/ise/1.1/user_guide/ise_man_id_stores.html#wp1054421
Strip start of subject name up to the last occurrence of the separator
Strip end of subject name from the first occurrence of the separator

Cisco ISE 1.1.2.145 Admin Authentication using LDAP

I have configured the LDAP and able to retrive our LDAP directory structure. Now, I am trying to point the 'Admin Access' authentication to "External Identity" Source which is the new LDAP IS I created. But I couldn't find an option to authenticate locally if for any reason the LDAP configuration doesn't work. I learnt that ISE can automatically revert to local auth provided the External Idenitity sources are unreachable. How can I test the LDAP authentication with out breaking our Admin Access? I thought of opening two parallel sessions, one with Super Admin Local Account and the other with Domain account. But I noticed that ISE communication is smart enough to logoff/login any other sessions in different browsers so basically I can't open two parallel sessions from same machine to do the tests. Suggestions? or Am I missing something here?
Many thanks in advance.

Hi Srinivas,
Even if you set up LDAP as an External Identity source for admin access, you can still fallback to Internal without getting locked out. As per the ISE user guide :
During operation, Cisco ISE is designed to "fall back" and attempt to perform authentication from the internal identity database, if communication with the external identity store has not been established or if it fails. In addition, whenever an administrator for whom you have set up external authentication launches a browser and initiates a login session, the administrator still has the option to request authentication via the Cisco ISE local database by choosing "Internal" from the Identity Store drop-down selector in the login dialog.
http://www.cisco.com/en/US/docs/security/ise/1.1/user_guide/ise_man_identities.html#wp1351543
Please refer to the attached screenshot from my lab ISE:
I have configured admin authentication against AD, but I still see both "Internal" and "AD" at the time of login.
Hope this helps.
Thanks,
Aastha

WLC AAA Radius to ISE - Multiple Domains in Single Forrest

I am currently having a problem configuring AAA for management access to our wireless controllers.
Our active directory structure is as below: (note all domains are part of the same forest and full trusts between the domains)
Root Domain
Americas domain UK Domain EU Domain APAC Domain
Because of the multiple domains that exist when admins login they need to use their full UPN ([email protected]), since just using username will only authenticate agains the Root Domain and there may be duplicate usernames between the domains.
I cant even see the radius request hitting ISE and i found out that this is due to a 24 character limit on the username field on the WLC's.
I dont have this issue with other IOS based devices.
I could just create some admin accounts in the root domain but the problem is that lobbyadmin staff also needs to authenticate and they will run into the same issue.
Dont know if someone has any suggestions for a possible workaround?
