Web Authentication - Web login page not displayed

Question

Cisco 4402 WLC running version 5.2.193.0
Access Points: AIR-LAP1142N
I have configured an SSID for WebAuthentication. When a wireless client logs into the WLAN the PC will associate to the AP but will then stop at the WEBAUTH_REQD stage.
Internet Explorer will show the attmept to redirect to the virtual port at 1.1.1.1 but will not bring up the login page.
IE shows : https://1.1.1.1/login.html?redirect=www.google.co.ukhttp://www.google.co.uk/
The network is a flat network so this SSID is using the management interface.
DHCP is being provided by the controller for this WLAN.
I know the classic design should be for this to be implemented on a separate VLAN but my customer has not VLANed his network yet and this is planned at a later stage. I have implemented this on a flat network before and it has worked.
Any suggestions would be much appreciated.

Answer 1

I faced exactly the same problem as you have described above. The following is what fixed it for me, i am sure u try it to might fix it for u as well.
In my scenario i found that my WLC controller had cipher-option sslv2 disabled. I enabled it and that resolved the issue for me.
This is what needs to be done in order to do it :-
It's best to enable it on the WLC and this is done from the CLI. It requires a reboot.
ssh to the WLC
enter the following command:-
WLC>config network secureweb cipher-option sslv2 enable
and then reboot.
Once the WLC reboots u can check the status by issuing the following command:-
WLC>show network summary
The output should look similar to the following
RF-Network Name............................. GTCR-CH-RF-GA
Web Mode.................................... Enable
Secure Web Mode............................. Enable
Secure Web Mode Cipher-Option High.......... Disable
Secure Web Mode Cipher-Option SSLv2......... Enable
As u can see the Secure Web Mode Cipher-Option SSLv2 is now enabled.
This should work.
Hope this helps and all the best.
