Disables support for SSL Version 2. Support for SSL V2 is enabled by default. The value yes means support is disabled. The value no means the support is enabled. This stanza entry is optional. When not specified, the default is no. Default value: no. The WebSEAL configuration sets this value Example: disable-ssl-v2 = no disable-ssl-v3 = {yes|no} Disables support for SSL Version 3. Support for SSL V3 is enabled by default. The value yes means support is disabled. The value no means the support is enabled. This stanza entry is optional. When not specified, the default is no. Default value: no. The WebSEAL configuration sets this value. Example: disable-ssl-v3 = no disable-tls-v1 = {yes|no} Disables support for TLS Version 1. Support for TLS V1 is enabled by default. The value yes means support is disabled. The value no means the support is enabled. This stanza entry is optional. When not specified, the default is no. Default value: no. The WebSEAL configuration sets this value. Example: disable-tls-v1 = no ssl-v2-timeout = number_of_seconds Session timeout in seconds for SSL v2 connections between clients and servers. This timeout value controls how often a full SSL handshake is completed between clients and WebSEAL. Valid range of values for number_of_seconds is from 1-100 seconds. This value is set by the WebSEAL configuration utility. This stanza entry is required when SSL is enabled. Default value: 100 Example: ssl-v2-timeout = 100 ssl-v3-timeout = number_of_seconds Session timeout in seconds for SSL v3 connections between clients and servers. This timeout value controls how often a full SSL handshake is completed between clients and WebSEAL. Valid range of values for number_of_seconds is from 1-86400 seconds, where 86400 seconds is equal to 1 day. If you specify a number outside this range, the default number of 7200 seconds will be used. This value is set by the WebSEAL configuration utility. This stanza entry is required when SSL is enabled. Default value: 7200 Example: ssl-v3-timeout = 7200 ssl-max-entries = number_of_entries 408 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Integer value indicating the maximum number of concurrent entries in the SSL cache. The minimum value is zero (0) which means that caching is unlimited. Entries between 0 and 256 are set to 256. There is no maximum limit. This stanza entry is optional. When the stanza entry is not assigned a value, WebSEAL uses a default value of 0. The WebSEAL configuration utility, however, assigns a default value of 4096. Example: ssl-max-entries = 4096 See also the IBM Tivoli Access Manager for e-business Performance Tuning Guide. gsk-crl-cache-size = number_of_entries Integer value indicating the maximum number of entries in the GSKit CRL cache. Minimum value is 0. A value of 0 means that no entries are cached. Neither WebSEAL nor GSKit impose a maximum value on this cache. See the discussion on maximum values for integers in “Guidelines for configuring stanzas” on page 378. See the Secure Socket Layer Introduction and iKeyman User’s Guide for more information on GSKit. See also the standards documents for SSL V3 and TLS V1 (RFC 2246) for more information on CRLs. This stanza entry is required. Default value: 0 Example: gsk-crl-cache-size = 0 gsk-crl-cache-entry-lifetime = number_of_seconds Integer value specifying the lifetime timeout, in seconds, for individual entries in the GSKit CRL cache. The minimum value is 0. The maximum value is 86400. Neither WebSEAL nor GSKit impose a maximum value on the cache entry lifetime. See the discussion on maximum values for integers in “Guidelines for configuring stanzas” on page 378. See the Secure Socket Layer Introduction and iKeyman User’s Guide for more information on GSKit. See also the standards documents for SSL V3 and TLS V1 (RFC 2246) for more information on CRLs. This stanza entry is required. Default value: 0 Example: gsk-crl-cache-entry-lifetime = 0 crl-ldap-server = server_name Name of the LDAP server to be referenced for Certificate Revocation List (CRL) checking during SSL authentication. This stanza entry is optional. There is no default value. Example: crl-ldap-server = surf.santacruz.ibm.com crl-ldap-server-port = port_number Appendix A. WebSEAL configuration file reference 409
