Info

Host name of the LDAP server. The WebSEAL configuration utility gets the host_name value from the pd.conf file. The pd.conf file is created when the Tivoli Access Manager runtime component is configured on the machine. The Tivoli Access Manager runtime component is a prerequisite for WebSEAL. Valid values for host_name include any valid IP host name. The host_name does not have to be a fully qualified domain name. This stanza entry is required. The default value is the value entered by the administrator during the configuration of the Tivoli Access Manager runtime component. Examples: host = surf host = surf.santacruz.ibm.com port = port_number Number of the TCP/IP port used for communicating with the LDAP server. Note that this is not for SSL communication. A valid port number is any positive integer that is allowed by TCP/IP and that is not currently being used by another application. This stanza entry is required when LDAP is enabled. Default value: 389. Example: port = 389 bind-dn = LDAP_dn LDAP user distinguished name (DN) that is used when binding (or signing on) to the LDAP server. This is the name that represents the WebSEAL server daemon. This stanza entry is required when LDAP is enabled. The default value is built by combining the daemon name webseald with the host_name that was specified by the administrator during the configuration of the Tivoli Access Manager runtime component. Example: bind-dn = cn=webseald/surf,cn=SecurityDaemons,secAuthority=Default See also the IBM Tivoli Access Manager for e-business Performance Tuning Guide. bind-pwd = LDAP_password Password for the LDAP user distinguished name declared in the bind-dn stanza entry. This stanza entry is required when LDAP is enabled. The default value of this stanza entry is set during WebSEAL configuration. The WebSEAL configuration reads the LDAP_password that was specified by the administrator during the configuration of the Tivoli Access Manager runtime component. This value is read from the Tivoli Access Manager configuration file, pd.conf. Example: bind-pwd = zs77WVoLSZn1rKrL cache-enabled = {yes|true|no|false} 394 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Enables or disable LDAP client-side caching. Caching is used to improve performance for similar LDAP queries. Valid values are: yes|true Enable LDAP client-side caching. no|false Disable LDAP client-side caching. Anything other than yes|true, including a blank value, is interpreted as no|false. This stanza entry is optional. Default value: disabled. When no value is specified (empty value), client-side caching is disabled. Example: cache-enabled = yes See also the IBM Tivoli Access Manager for e-business Performance Tuning Guide. cache-user-size = number Specifies the number of entries in the LDAP user cache. This entry is used only when cache-enabled = {yes|true}. This stanza entry is optional. There is no default value, but when not set the default value used is 256. Example: cache-user-size = 256 cache-group-size = number Specifies the number of entries in the LDAP group cache. This entry is used only when cache-enabled = {yes|true}. This stanza entry is optional. There is no default value, but when not set the default value used is 64. Example: cache-group-size = 64 cache-policy-size = number Specifies the number of entries in the LDAP policy cache. This entry is used only when cache-enabled = {yes|true}. This stanza entry is optional There is no default value, but when not set the default value used is 20. Example: cache-policy-size = 20 cache-user-expire-time = number_of_seconds Specifies the amount of time to elapse before a user entry in the cache is discarded. This entry is used only when cache-enabled = {yes|true}. This stanza entry is optional. There is no default value, but when not set the default value used is 30 seconds. Example: cache-user-expire-time = 30 Appendix A. WebSEAL configuration file reference 395
