I would like to configure my Cisco VPN 3000 to support the windows password expiration.
I followed this tutorial : http://www.cisco.com/en/US/products/hw/vpndevc/ps2284/products_configuration_example09186a00800946b9.shtml#
In my architecture, the VPN 3000 uses an ACS 3.3 as a radius server that is connected to a windows database (AD domain).
When I force my password to expire and try to connect through VPN (Cisco VPN Client 5.05), I have the prompt to change the password (PIN it said) but when I try to enter the new password and click OK, it tries to connect again and reply the following error : "Unknow Error occured at peer"
When I check the ACS log, I get the two following messages :
1. "Windows user must change password"
2. "Internal error"
How can I investigate this error and solve this ?
Thank you !
