Info

Backwards compatibility WebSEAL servers prior to Version 5.1 did not use UTF-8 encoding. Thus, cookies created by these servers do not have UTF-8 encoding on their strings. When a WebSEAL server is operating with WebSEAL servers from versions prior to Version 5.1, WebSEAL should not use UTF-8 encoding. For backwards compatibility, set use-utf8 to no. [failover] use-utf8 = no For more information on WebSEAL support for UTF-8 encoding, see “Multi-locale support with UTF-8” on page 44. Add the authentication level To specify authentication level in the failover authentication cookie, add the authentication level to the WebSEAL configuration file. You must use the stanza entry keyword AUTHENTICATON_LEVEL: [failover-add-attributes] AUTHENTICATION_LEVEL = add The actual value for AUTHENTICATION_LEVEL is an integer that WebSEAL tracks internally. You do not need to specify the integer in this stanza. Add the session lifetime timestamp WebSEAL calculates the session lifetime timestamp by combining the following values: v Current system time. v Maximum lifetime in seconds that an entry is allowed to exist in the WebSEAL credential cache. This maximum lifetime in seconds is specified in the WebSEAL configuration file [session] stanza: [session] timeout = 3600 To add this value to the failover authentication cookie, add the following entry to the WebSEAL configuration file: [failover-add-attributes] session-lifetime-timestamp = add Note that this attribute cannot be set by wildcard matching. The exact entry session-lifetime-timestamp must be entered. Add the session activity timestamp WebSEAL calculates the session activity timestamp by adding together these values: v System time. v Maximum lifetime of inactive entries in the credential cache. The maximum lifetime for inactive entries is set in the [session] stanza in the WebSEAL configuration file: [session] inactive-timeout = 600 The default value is 600 seconds. v Interval for updating the failover authentication cookie. 176 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
This value is set in the [failover] stanza in the WebSEAL configuration file: [failover] failover-update-cookie = 60 The default value is 60 seconds. For more information, see “Add an interval for updating the activity timestamp.” To add this value to the failover authentication cookie, add the following entry to the WebSEAL configuration file: [failover-add-attributes] session-activity-timestamp = add Note that this attribute cannot be set by wildcard matching. The exact entry session-activity-timestamp must be entered. Note: When you set failover-update-cookie to a number greater than zero, ensure that you also set session-activity-timestamp = add. If you do not set session-activity-timestamp = add, WebSEAL will decode the failover cookie on each user access. This could adversely affect performance. Add an interval for updating the activity timestamp Optionally, the session activity timestamp in the failover cookie can be updated during the user’s session. This entry contains an integer value for interval (in seconds) between updating the failover cookie’s activity timestamp. The default entry is: [failover] failover-update-cookie = 60 When failover-update-cookie is set to 0, the last activity timestamp is updated with each request. When failover-update-cookie is set to an integer less than 0 (any negative number), the last activity timestamp is never updated. When failover-update-cookie is set to an integer greater than 0, the session activity timestamp in the cookie is updated at intervals of this number of seconds. The value chosen for this stanza entry can affect performance. See “Addition of data to a failover cookie” on page 168. Note: When you set failover-update-cookie to a number greater than zero, ensure that you also set session-activity-timestamp = add. If you do not set session-activity-timestamp = add, WebSEAL will decode the failover cookie on each user access. This could adversely affect performance. See “Add the session activity timestamp” on page 176. Add extended attributes WebSEAL can optionally be configured to place a copy of specified extended attributes from a user credential into a failover authentication cookie. No extended attributes are configured by default. To add extended attributes, add entries to the [failover-add-attributes] stanza in the WebSEAL configuration file. The syntax is: Chapter 6.
