Table 18. Authentication errors (continued) Account lock-out 13212132 320938290 Account lock-out: user Expired password 132120cc 320938188 The user’s password has expired. General failure All others All others user To determine the reason for an audited event such as an account lock-out (due, for example, to a three strikes policy), obtain the error code as shown in the table above. The error code is contained in the audit output in the tag: "13212132">0 Invoke the pdadmin errtext command for the error code to receive a reason for the outcome. For example: > pdadmin errtext 13212132 This account has been temporarily locked out due to too many failed login attempts Error codes for Tivoli Access Manager are described in the IBM Tivoli Access Manager Error Message Reference. Audit data in UTF-8 format WebSEAL produces audit data using UTF-8 encoding. When the operating system uses a non-UTF-8 local code page, WebSEAL automatically converts audit data to a data format to match the non-UTF-8 local code page. In some cases, the conversion from UTF-8 to non-UTF-8 encoding can result in data loss. For this reason, it is recommended that the WebSEAL process run in a locale environment that uses UTF-8 encoded code pages. It is possible to obtain UTF-8 logs when running in a non-UTF-8 locale. Use the UTF8FILE type in the routing file. Note that when data loss occurs, the audit file entry contains a series of question marks (????) at the location where data conversion was problematic. For more information, see “Multi-locale support with UTF-8” on page 44. 104 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Legacy auditing Legacy auditing is configured by supplying a value for each the following keys: [aznapi-configuration] logaudit auditlog auditcfg logsize logflush Use of this method is comparable to the event logging method, when directing output to a file. Note, however, that the event logging method provides additional control over buffer size and event queues. Also, legacy auditing does not support output to consoles, pipes, or remote servers. Legacy auditing for authentication To use legacy auditing to accomplish the configuration tasks for the authentication auditing example above, the comparable configuration file entries would be: [aznapi-configuration] logaudit = yes auditcfg = authn auditlog = /var/pdweb/log/audit.log logsize = 2000000 logflush = 20 Legacy auditing does not support the optional configuration settings. For more information on legacy auditing configuration settings, see IBM Tivoli Access Manager Base Administration Guide. Legacy auditing for HTTP WebSEAL maintains three conventional HTTP log files that record activity rather than messages: v request.log v agent.log v referer.log By default, these log files are located under the following directory: UNIX: /var/pdweb/www/log/ Windows: C:\Program Files\Tivoli\PDWeb\www\log\ Parameters for configuring standard HTTP logging are located in the [logging] stanza of the WebSEAL configuration file. The following table illustrates the relationship between the HTTP log files and the configuration file parameters: Log Files Location Parameter Enable/Disable Parameter ( = yes or no) request.log requests-file requests Chapter 4.
