Authenticate with Microsoft LDAP

Reuven Elkabetz — Mon, 11 Mar 2019 23:34:49 GMT

Hi all,

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

vpn-session-timeout none

vpn-filter value DDD-Basic

vpn-tunnel-protocol IPSec

vpn-framed-ip-address 1.1.1.1 255.255.255.0

password-storage enable

group-lock value Basic

Is it possible to live the user attributes as is and to force the users to authenticate via LDAP servers only?

Hello Ramraj,

Thanks a lot to your reply, sorry for the delay, but now I have a chance to verify again the above issue and according to the debug I triggered in ASA (225) , it is getting the right user and recognize it correct. I had no errors. But I am still getting en error from the VPN client. The error I received is "Secure VPN connection terminated locally by the client. Reason 413: User authentication failed." I also tried to get an IP from AD withput success. Any Idea ?

Thanks, a lot,

Reuven

Hello Ramraj,

Sorry for the delay, but yesterday I had a chance to check again and to test what I configured accroding to the document that you sent me a while ago (:-)). I triggered the debug on the ASA 5520 and everything looks fine. The LDAP server is sending the right information without any error message. In the VPN client when I am trying to login I am receiving the following error message:

"Secure VPN connection terminated locally by the client. Reason 413:User authentication failed" . 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.

Any idea what could be the reason?

Thanks alot ,
