SSL VPN, "Login failed" and "WebVPN: error creating WebVPN session!"

Unanswered Question
Nov 3rd, 2010

Hi,

Just ran the wizard for Anyconnect SSL VPN, created a tunnel group, a vpn pool and added user to it. When trying to logon on the SSL service, it simply says "login failed". I suspect that the user might not be in correct groups or so?

some relevant config

webvpn
enable wan
svc image disk0:/anyconnect-win-2.4.1012-k9.pkg 1
svc enable
group-policy vpnpolicy1 internal
group-policy vpnpolicy1 attributes
vpn-tunnel-protocol svc
tunnel-group admins type remote-access
tunnel-group admins general-attributes
address-pool sslpool2
default-group-policy vpnpolicy1
!

username myuser password 1234567890 encrypted privilege 15
username myuser  attributes
vpn-group-policy vpnpolicy1

Hi ,

Please make sure HTTP service is enabled on the ASA with the command "http server enable". But you said you used the wizard to configure Anyconnect, so i think this is already present.

Also please provide the output of "sh run http" from the ASA. Also please run the debug "debug http" and let us know the output.

Cheers,

Rudresh V

AnyConnect says:

"The secure gateway has rejected the agents VPN connect or reconnect request. A new connection requires re-authentication and must be started manually. Please contact your network administrator if this problem persists.

The following message was received from the secure gateway: Host or network is 0"

Other resources indicate that it's either the tunnel group, or the address pool.. The address pool is:

ip local pool sslpool2 172.16.20.0-172.16.20.254 mask 255.255.255.0

I encountered this error message when I exceeded the number of licensed WebVPN connections. We were using the 2 "free" licenses. When the 3rd simultaneous connection was attempted, RADIUS would grant the connection, but a debug on the ASA showed this error:

WebVPN: user: (jdoe) authenticated.

webvpn_auth.c:http_webvpn_auth_accept[3121]

webvpn_session.c:http_webvpn_create_session[184]

WebVPN: error creating WebVPN session!

This is different than your debug though, so it might not apply. On the user side in the webvpn interface they got a "login failed" error.
