AuthType type For Kerberos authentication to work, AuthType must be set to 'Kerberos'. For the reasons of backwards compatibility the values KerberosV4 and KerberosV5 are also supported. Their use is not recommended though, for finer setting use following three options. KrbMethodNegotiate on | off (set to on by default) To enable or disable the use of the Negotiate method. You need a special support on the browser side to support this mechanism. KrbMethodK5Passwd on | off (set to on by default) To enable or disable the use of password based authentication for Kerberos v5. KrbMethodK4Passwd on | off (set to on by default) To enable or disable the use of password based authentication for Kerberos v4. KrbAuthoritative on | off (set to on by default) If set to off this directive allow authentication controls to be pass on to another modules. Use only if you really know what you are doing. KrbAuthRealms realm1 [realm2 ... realmN] This option takes one or more arguments (separated by spaces), specifying the Kerberos realm(s) to be used for authentication. This defaults to the default realm taken from the local Kerberos configuration. KrbVerifyKDC on | off (set to on by default) This option can be used to disable the verification tickets against local keytab to prevent KDC spoofing atacks. It should be used only for testing purposes. You have been warned. KrbServiceName server_principal Specifies a principal name to use by Apache when authenticating the clients. By default value of the form HTTP/@ is used. The FQDN part can contain any hostname and can be used to work around problems with misconfigured DNS. A corresponding key of this name must be stored in the keytab. If this option is set to 'Any', then any prinicpal from the keytab which matches the client's request may be used. Krb4Srvtab /path/to/srvtab This option takes one argument, specifying the path to the Kerberos V4 srvtab. It will simply use the "default srvtab" from Kerberos V4's configuration if this option is not specified. The srvtab must be readable for the apache process, and should be different from srvtabs containing keys for other services. Krb5Keytab /path/to/keytab This option takes one argument, specifying the location of the Kerberos V5 keytab file. It will use the "default keytab" from Kerberos V5's config if it is not specified here. The keytab file must be readable for the apache process, and should be different from other keytabs in the system. KrbSaveCredentials on | off (set to off by default) This option enables credential saving functionality. KrbDelegateBasic on | off (set to off by default) If set to 'on' this options causes that Basic authentication is always offered regardless setting the KrbMethodK[45]Pass directives. Then, if a Basic authentication header arrives authentication decision is passed along to another modules. This option is a work-around for insufficient authentication scheme in Apache (Apache 2.1 seems to provide better support for multiple various authentication mechanisms).
