Hi,
I am trying to get cut through proxy to authenticate SSH connectivity. If I use telnet, the firewall will proxy correctly and force local AAA authentication however, when using SSH, the connection is dropped with error :
processing uauth_error, session id: 2147483663, message: Must authenticate before using this service.
Why does the firewall not enforce AAA authentication when connecting using SSH rather than telnet??
Configured on ASA5510 SP - version 8.
Please assist?
Thanks!

Saron,
On ASA you cannot use SSH to authenticate for CTP.
Supported authentication protocols:
http://www.cisco.com/en/US/docs/security/asa/asa82/configuration/guide/access_fwaaa.html#wp1061184
We'd need to somehow do a man in the middle attach on SSH flows to make CTP work with SSH.
Hope this helps,
Marcin
