Hi, I'm opening a new topic related to my problem with the VPN connection, to avoid confusion, since there are many, in the old information, no longer required.
I would like to configure my ASA5510 L2PT/IpSec to accept connections from Windows clients.
I happen to authenticate via AD credentials.
When I try to connect is because the error 691.
I enabled debugging on the machine the following:
debug crypto isakmp 3
debug crypto ipsec 3
debug ldap 255
I tried it with different operating systems (XP and seven), but I always get the same error.
I set the client in this way:
Security -> VPN type -> L2TP/IPSec
Encryption -> require encryption (disconnect in case of refusal)
protocols -> microsoft CHAO ver 2 (only)
Advanced Settings -> pre-shared key
the domain user that is used is able to receive incoming calls.
testing ldap authentication is successful. With the same credentials i can connect to the SSL portal without any problems and I see all shared resources
as seen, from the debug, the call to authenticate ldap user is never made.
I hope I can help solve this problem, thanks
