Configuring the Maximum Object Size to Ignore for Updating the Session Timer
Network devices exchange short keepalive messages to ensure that the virtual circuit between them is
still active. The length of these messages can vary. The keep-alive-ignore command lets you tell the
security appliance to consider all messages that are less than or equal to the specified size as keepalive
messages and not as traffic when updating the session timer. The range is 0 through 900 KB. The default
is 4 KB.
To specify the upper limit of the HTTP/HTTPS traffic, per transaction, to ignore, use the
keep-alive-ignore command in group-policy attributes webvpn configuration mode:
hostname(config-group-webvpn)# keep-alive-ignore size
hostname(config-group-webvpn)#
The no form of the command removes this specification from the configuration:
hostname(config-group-webvpn)# no keep-alive-ignore
hostname(config-group-webvpn)#
The following example sets the maximum size of objects to ignore as 5 KB:
hostname(config-group-webvpn)# keep-alive-ignore 5
hostname(config-group-webvpn)#
Configuring Auto-Signon
To automatically submit the login credentials of a particular user of clientless SSL VPN to internal
servers using NTLM, basic HTTP authentication or both, use the auto-signon command in username
webvpn configuration mode.
The auto-signon command is a single sign-on method for users of clientless SSL VPN sessions. It passes
the login credentials (username and password) to internal servers for authentication using NTLM
authentication, basic authentication, or both. Multiple auto-signon commands can be entered and are
processed according to the input order (early commands take precedence).
You can use the auto-signon feature in three modes: webvpn configuration, webvpn group configuration,
or webvpn username configuration mode. The typical precedence behavior applies where username
supersedes group, and group supersedes global. The mode you choose will depend upon the desired
scope of authentication.
To disable auto-signon for a particular user to a particular server, use the no form of the command with
the original specification of IP block or URI. To disable authentication to all servers, use the no form
without arguments. The no option allows inheritance of a value from the group policy.
The following example commands configure auto-signon for a user of clientless SSL VPN named
anyuser, using either basic or NTLM authentication, to servers defined by the URI mask
https://*.example.com/*:
hostname(config)# username anyuser attributes
hostname(config-username)# webvpn
hostname(config-username-webvpn)# auto-signon allow uri https://*.example.com/* auth-type
all
The following example commands configure auto-signon
anyuser, using either basic or NTLM authentication, to the server with the IP address
10.1.1.0, using subnet mask 255.255.255.0:
hostname(config)# username anyuser attributes
hostname(config-username)# webvpn
hostname(config-username-webvpn)# auto-signon allow ip 10.1.1.0 255.255.255.0 auth-type
all
hostname(config-username-webvpn)#
