Info

String that specifies the key label of the client personal certificate within the SSL key file. This key label is used to identify the client certificate that is presented to the LDAP server. This stanza entry is optional. A label is not required when one of the certificates in the keyfile has been identified as the default certificate. The decision whether to identify a certificate as the default was made previously by the LDAP administrator when configuring the LDAP server. The WebSEAL configuration utility prompts the WebSEAL administrator to supply a label. When the administrator knows that the certificate contained in the keyfile is the default certificate, the administrator does not have to specify a label. Example: ssl-keyfile-dn = "PD_LDAP" ssl-keyfile-pwd = password Password to access the SSL key file. The password associated with the default SSL keyfile is gsk4ikm Required only when SSL communication between WebSEAL and LDAP is enabled, as specified in the ssl-enabled stanza entry. The WebSEAL administrator specifies this password during WebSEAL configuration. Example: ssl-keyfile-pwd = gsk4ikm auth-using-compare = {yes|true|no|false} Enables or disables authentication using password comparison. When disabled, authentication using LDAP bind is performed. For those LDAP servers that allow it, a compare operation might perform faster than a bind operation. Valid values are: yes|true A password compare operation is used to authenticate LDAP users. no|false A bind operation is used to authenticate LDAP users. This stanza entry is optional. The default value, when LDAP is enabled, is yes. Example: auth-using-compare = yes See also the IBM Tivoli Access Manager for e-business Performance Tuning Guide. default-policy-override-support = {yes|true|no|false} 398 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Indicates whether default policy overrides user level policy during LDAP searches. When this stanza entry is set to yes, only the default policy is checked. Valid values are: yes|true User policy support is disabled and only the global (default) policy is checked. This option allows the user policy to be ignored, even when it is specified. no|false User policy support is enabled. When a user policy is specified by the administrator, it overrides the global policy. This stanza entry is optional. By default, the value is not specified during WebSEAL configuration. When the value is not specified, the default behavior is enable user policy support. This is equivalent to setting this stanza entry to no. Example: default-policy-override-support = yes user-and-group-in-same-suffix = {yes|true|no|false} Indicates whether the groups, in which a user is a member, are defined in the same LDAP suffix as the user definition. When a user is authenticated, the groups in which the user is a member must be determined in order to build a credential. Normally, all LDAP suffixes are searched to locate the groups of which the user is a member. Valid values are: yes|true The groups are assumed to be defined in same LDAP suffix as the user definition. Only that suffix is searched for group membership. This behavior can improve the performance of group lookup because only a single suffix is searched for group membership. This option should only be specified if group definitions are restricted to the same suffix as the user definition. no|false The groups might be defined in any LDAP suffix. This stanza entry is optional. The value is not specified by default during WebSEAL configuration. When the value is not specified, the default value is no. Example: user-and-group-in-same-suffix = yes See also the IBM Tivoli Access Manager for e-business Performance Tuning Guide. Appendix A. WebSEAL configuration file reference 399
