[failover-add-attributes] attribute_pattern = add The attribute_pattern can be either a specific attribute name, or a case-insensitive wildcard expression that matches more than one attribute name. For example, to specify all attributes with the prefix tagvalue_, add the following entry: [failover-add-attributes] tagvalue_* = add The order of the stanza entries is important. Rules that appear earlier in [failover-add-attributes] take priority over those placed later in the stanza. Attributes that do not match any of the wildcard patterns, or are not explicitly specified, are not added to the failover cookie. Specify the authentication level attribute after failover authentication When a failover cookie is used to authenticate, an authentication level can be associated with the generated credential. This can be done in the following ways: v Using a flag to the failover-* authentication mechanism. You can set the authentication level based on the last authentication method used. This is done by passing a flag to the authentication method. The syntax is: [authentication-mechanisms] failover-method_name = WebSEAL_failover_lib -i authentication_level For example: failover-password = /opt/pdweb/liblibfailoverauth.so& -i 1 failover-token = /opt/pdweb/liblibfailoverauth.so& -i 2 failover-certificate = /opt/pdweb/liblibfailoverauth.so& -i 3 Note: This method can be used only with the built-in WebSEAL failover authentication library. This method is not available to custom authentication modules. v Setting it in the [failover-restore-attributes] configuration file stanza entry. This attribute can specify whether to use the authentication level from the failover cookie, if it exists: [failover-restore-attributes] AUTHENTICATION_LEVEL =preserve Specify attributes for extraction WebSEAL can optionally be configured to extract attributes from a failover authentication cookie and place them into a user credential. No attributes are configured for extraction by default. Attributes to be extracted are declared in the [failover-restore-attributes] stanza in the WebSEAL configuration file. The syntax is: [failover-restore-attributes] attribute_pattern = {preserve|refresh} The value preserve tells WebSEAL to extract the attribute and add it to the credential. The value refresh tells WebSEAL to ignore the attribute, and not extract it from the cookie. 178 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
The attribute_pattern can be either a specific attribute name, or a case-insensitive wildcard expression that matches more than one attribute name. For example, to extract all attributes with the prefix tagvalue_, add the following entry: [failover-restore-attributes] tagvalue_* = preserve Attributes that do not match any patterns specified with the preserve value are not extracted from the failover authentication cookie. The order of the stanza entries is important. Rules that appear earlier in [failover-restore-attributes] take priority over those placed later in the stanza. The following attributes cannot be matched by a wildcard pattern, but must be explicitly defined for extraction: v Authentication level [failover-restore-attributes] AUTHENTICATION_LEVEL = preserve v Session lifetime timestamp [failover-restore-attributes] session-lifetime-timestamp = preserve v Session inactivity timestamp [failover-restore-attributes] session-inactivity-timestamp = preserve Enable domain-wide failover cookies You can allow a failover authentication cookie to be used by any WebSEAL server within the same domain as the WebSEAL server that creates the cookie. This feature is controlled by a stanza entry in the [failover] stanza. By default, domain-wide failover cookie functionality is disabled: [failover] enable-failover-cookie-for-domain = no To enable this feature, set enable-failover-cookie-for-domain to yes: [failover] enable-failover-cookie-for-domain = yes For information on the effects of enabling this stanza entry, see “Domain-wide failover authentication” on page 171. Require validation of a lifetime timestamp WebSEAL servers can optionally be configured to require that each failover authentication cookie contain a session lifetime timestamp. The session lifetime timestamp is not required by default. The default configuration file entry is: [failover] failover-require-lifetime-timestamp-validation = no This stanza entry is used primarily for backwards compatibility. Attention: For backwards compatibility with failover cookies created by WebSEAL servers prior to Version 5.1, set this entry to no. Failover authentication cookies created by WebSEAL servers prior to Version 5.1 do not contain this timestamp. Chapter 6. Authentication 179
